Marla draws a diagonal in a rhombus to form two triangles. What term can she use to classify each triangle? Explain.


A.

Acute; a rhombus always has 2 acute angles so the 3 angles in each triangle must all be acute.


B.

Equilateral; since a rhombus always has 4 equal sides, each triangle must have 3 equal sides.


C.

Isosceles; since a rhombus always has 4 equal sides, each triangle must have 2 equal sides.


D.

Obtuse; a rhombus always has 2 obtuse angles so each triangle must have an obtuse angle.


Please answer ASAP

Answer 1

Answer: It's C because It was correct on my test.

If I wrong i'm really sorry

Step-by-step explanation:

Answer 2

C. Isosceles; since a rhombus always has 4 equal sides, each triangle must have 2 equal sides.

What is an Isosceles Triangle?

An Isosceles Triangle is defined as a triangle with two sides of equal length is an isosceles triangle.

A rhombus is a quadrilateral with all four sides congruent, or equal in length. When a diagonal is drawn in a rhombus, it will always divide the rhombus into two congruent triangles. Since the opposite sides of a rhombus are congruent, the two triangles formed by the diagonal will always have two congruent sides. Therefore, each triangle is an isosceles triangle.

A rhombus can have angles of various degrees. It can have angles more than 90 degrees, less than 90 degrees, or 90 degrees which means the statements A, and D are incorrect.

B is incorrect because the triangles formed by the diagonal of a rhombus will not have 3 equal sides, because the diagonal will not be congruent with the sides.

Hence, the correct answer would be an option (C).

In ABC, the interior angle at A is 51° and the exterior angle at B is 119º. The interior angle at C measures
A 51°
B 68°
C 90°
D 39°

Answers

Answer:

68 degrees

Step-by-step explanation:

To get the interior angle, we use an important triangle principle

The principle is that the sum of the opposite interior angles equal the exterior angle

Let the second interior angle be x

x + 51 = 119

x = 119-51

x = 68

What is the measure of the third angle

Answers

58

a right triangle is 90 degrees so you subtract 32 from 90 to find the remainder

Answer:

The third angle is 58 degrees

Step-by-step explanation:

In a triangle all three angles add up to 180 degrees. If you know two sides, add them up then subtract the sum from 180. This will leave you with the last angle measurement.

In a right triangle we always know there is one angle that has a measure of 90 degrees. So now we know two angles 90 and 32.

90 + 32 = 122

180 - 122 = 58


11. The price of a bottle of water at a store decreases from $1.65 to $1.40. Rounded to the nearest
tenth of a percent, what is the percent decrease in the price of the bottle of water?
A. 15.2%
B. 17.9%
C. 45.9%
D. 54.1%

Answers

Answer:

A. 15.2%

Step-by-step explanation:

Subtract the new price from the old one to find the dollar amount that the water bottle price was reduced.

[tex]1.65-1.40=0.25[/tex]

The price was reduced by 25 cents, but we need to find the percentage. To do that, we divide the price reduction by the original price.

[tex]0.25/1.65=0.152[/tex]

And then move the decimal place over two spots (multiply by 100)

15.2

Percent decrease in the price of the bottle of water is 15.2% (Approx.)

Given that;

Older price of bottle = $1.65

New price of bottle = $1.40

Find:

Percent decrease in the price of the bottle of water

Computation:

Percent decrease in the price of the bottle of water = [(1.65 - 1.40) / 1.65]100

Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100

Percent decrease in the price of the bottle of water = [(0.25) / 1.65]100

Percent decrease in the price of the bottle of water = 15.2% (Approx.)

The parallelogram shown below has an area of 21 units?.
7

Find the missing base.
b=
units

Answers

Answer:

The missing base b is 3 units

Step-by-step explanation:

The parallelogram has two different bases, b1 and b2Each base has a height perpendicular to it from the base parallel to ith1 is the height of b1 and h2 is the height of b2The formula of the area of the parallelogram is A = b1 × h1 = b2 × h2

Let us solve the problem

In the given figure

The given figure is a parallelogram

∵ The line of length 7 is perpendicular to the base that parallels to base b

∵ The base b has a height of 7 units

→ By using the formula of the area above

∵ A = b1 × h1

b1 = b and h1 = 7 units

∵ The parallelogram has an area of 21 square units

A = 21

→ Substitute the value of A and h in the rule of the area

21 = b × 7

∴ 21 = 7b

→ Divide both sides by 7

3 = b

The missing base b is 3 units
