Thanks~ Ill give brainliest

Answer:

CE= 9cm, DE= 5cm, CD= 10.2956cm

Step-by-step explanation:

Let E be the point of the other triangle.

Using Pythagoras' Theorem,

CD= square root symbol (CE^2 + DE^2)

= square root symbol (9^2+5^2)

= 10.2956cm (6 sf)

Answer:

D. 204 [tex]ft^{2}[/tex]

Step-by-step explanation:

the center square 11b x 12h = 132

17 - 11 = 6/2 = 3 this is the base for each of those right angles

3 x 12 = 36 x 2 = 72

132 + 72 = 204 [tex]ft^{2}[/tex]

Answer:

its d i think sorry if im wrong

Step-by-step explanation:

Answer:

N.14 ABC = 5x+20, N.15 ABE = 90. N.16. 123, 29, 28. N.17 K = 80

Step-by-step explanation:

Because of vertical angles, 5x+20 = 3x+66.

5x=3x+46

2x = 46

x = 23

Sum of angles in a circle is 360

360-135-135=180

ABE = CBD because vertical angles.

180 / 2 = 90

16.

Sum of angles in triangle is 180

180=123-x-2-x-3

x = 31

123, 29, 28.

17.

Sum of angles in triangle is 180

180-72-28 = 80

K = 80

no idea

Answer:

C) more than one triangle

Step-by-step explanation:

Answer:

The answer is D

Step-by-step explanation:

This is because the x value didn't change while the y values became negative.

9: 9 multiplied by y

10:x minus eight equals fourteen

11: y divided by twelve equals 24

12: k plus twelve

hope i helped!

Answer:

9)  9 times a number

10)  14 is the difference between a number and 8

11)  24 is the quotient of a number and 12

(or "24 is a number divided by 12")

12)  A number increased by 12

Step-by-step explanation:

There are several ways of writing these into a verbal phrase, but this is how I would do it:

9)  9 times a number

10)  14 is the difference between a number and 8

11)  24 is the quotient of a number and 12

(or "24 is a number divided by 12")

12)  A number increased by 12

Answer:

the answer is 10

Step-by-step explanation:

Answer for Practice 8-4:

1. Right, Scalene

2. Acute, Isosceles

3. Obtuse, Scalene

4. Isosceles

5. Scalene

6. Equilateral

7. Scalene

8. Acute

9. Obtuse

10. Right

11. Right

12. This cannot be done because a right triangle always has two acute angles (cannot be right-angled and obtuse-angled at the same time)

14. Can't be done because a scalene triangle has no congruent sides, while isosceles triangles have two equal sides and two equal angles.

Answer:

x =1+i√11/2,1−i√11/2

Step-by-step explanation:

/2 means that everything before it is divided by 2. Basically, each side is divided by 2, it just wont let me do that function on here ;)

Answer:

Step-by-step explanation:

The square root of 120 is 10.9 or rounded to 11

Hope this helps!

Special right triangles are triangles whose sides are in a particular ratio, known as Pythagorean Triples. In geometry, the Pythagorean Theorem is a statement that shows the relationship of the sides of a right triangle. ... The two special right triangles include: 45°; 45°; 90° Triangle

(BRAINLIEST PLEASE)

for 1 serving the ratio is 1 : 2

for 2 servings the ratio is 2 : 4

so by looking at the two ratios above you can see that

for two servings the ratio 1 : 2 is multiplied by two

so the answer for 5 servings is 5 : 10

so no matter the number of servings when you simplify the ratio the ratio you should obtain (as in this case) should be 1:2 which the ratio for 1 serving.

hope this helped :)

Let's say we start with the true statement that 2 < 5

Multiplying each of those numbers by -1 means we have...

If the inequality sign stayed the same, then we'd have the false statement -2 < -5. Use a number line to see why this is false. Note how -2 is to the right of -5, so it should be larger.

To fix this error, we flip the inequality sign.

So we go from 2 < 5 to -2 > -5

Rule: Multiplying both sides by a negative number always flips the inequality sign.

Step-by-step explanation:

[tex]\frac{5^2*5^6}{5^4}=5^?\\ \\\frac{5^{2+6}}{5^4}=5^?\\ \\\frac{5^8}{5^4}=5^?\\\\5^{8-4}=5^?\\\\5^4=5^?\\\\?=4[/tex]

[tex] \frac{5 {}^{2} \times {5}^{6} }{5 {}^{4} } \\ { \frac{5}{5 {}^{4} } }^{2 + 6} \\ \frac{ {5}^{8} }{5 {}^{4} } \\ 5 {}^{8 - 4} \\ 5 {}^{4} [/tex]

so 5⁴ is the answer

Answer:

The x's in the coordinates are not supposed to be negative; the y's should be negative instead.

Step-by-step explanation:

If the x's are negative, it will flip the triangle over the y-axis; therefore, the y's have to be negative instead, which will flip it over the x-axis.

Answer:

The x's in the coordinates are not supposed to be negative; the y's should be negative instead.
