Whats the supplementary angle of 109 degrees.

Answers

Answer 1

Answer:

Answer is 71°

Step-by-step explanation:

Two angles are said to be

supplementary angles if their

sum is 180°.

******************************************

one angle ( x ) = 109°

Let the second angle = y

x + y = 180°

=> y = 180° - x

=> y = 180° - 109°

=> y = 71°

So,

Supplementary angle of 109° should be 71°

I hope this helps

1) y = 1x + 95.50
x = number of bandanas

2) y = (1 • 50) + 95.50
$145.50 for 50 bandannas

3) 116.50 = 1x + 95.50
get x by itself

116.50 = 1x+ 95.50
-95.50 -95.50

21 = 1x
divide by 1
21 = x
you get 21 bandannas when you pay $116.50

Answer:

1. y=x+95.50

2. $145.5 (because 50 + 95.50)

3. 21 bandanas (because 116.5-95.5)

Not sure if you wanted answers or explanation on what to do. Ill just do the explanation and if you want the answers just lmk C:

R=1/2 d, and C=pi*2r. So you basically take the given number and plug it into these formulas.

Answer:

21. D = 5.67(rounded to the hundredths)

R = 2.84(rounded to the hundredths)

22. D = 13.4

C = 42.08(rounded to the hundredths)

23. C = 33.28(rounded to the hundredths)

R = 5.3

24. D = 1

R = 1.57 or pi/2

Step-by-step explanation:

Formula: C/pi = D

D = 2r

pi = 3.14

21. D = 17.8/3.14 = 5.67(rounded to the hundredths)

R = 5.67/2 = 2.84(rounded to the hundredths)

22. D = 6.7*2 = 13.4

C = 13.4 * 3.14 = 42.08 (rounded to the hundredths)

23. C = 10.6 * 3.14 = 33.28(rounded to the hundredths)

R = 10.6/2 = 5.3

24. D = 3.14/3.14 = 1

R = 3.14/2 = 1.57 or pi/2

Area of a triangle is base x height so for the first one you would have to do:
A= 6x14
So area equals
84

Answer:

Triangle:

In order for you to solve all of them you need to multiply the base times the height then divide that in half.

example answer;

3 is 68 because you multiply 17 by 8 then divide in half.

Decomposition of the trapezoid to find the area. You first need to separate the parts of the trapezoid that make a triangles. Ex: separate the outer parts so that you're left with triangle/s and a rectangle/square shape in the middle. Find the area of the triangles and the area of the middle square/rectangle and then add that together.

8. 171 I used this formula A=(a+b)h/2  Which is top length+bottom length times height divided by two.

Trapezoid area:

You need to add the top base and the bottom base together then multiply that by the height.

9. 396. I  used the same formula as the last one. which is A=(a+b)h/2.

Step-by-step explanation:

Ok, I might be super-duper wrong, but please don't hate me!!!

I think the answer is C. because to know how much money you need, you need to find how much something costs.

It also asks for you to answer the first step, or find the perimeter.

Formula of perimeter = b2 + w2 (base times two plus the width times two).

6 1/4 * 2 = 12.5

11 1/4 * 2 = 22.5

12.5 + 22.5 = 35.
