Hey there! :D

So, those both will be equal to 180 degrees. Consecutive angles are supplementary. 

2x-20+3x= 180

5x-20=180

Add 20 to both sides.

5x=200

x= 40

I hope this helps!

2x-20+3x=180
Add like terms
5x-20=180
Add 20 on both sides
5x=200
Divide by 5 on both sides
X=40

HELP IMMEDIATELY!!
Rashid [163]

Answer:

The value of c is 3

Step-by-step explanation:

Here, we want to get the value of c

From the question, we can select a single x-point

when x = 16

f(x) = 2

g(x) = -1

Thus;

g(16) = f(16) - c

-1 = 2 - c

c = 2 + 1

c = 3

-25 Points-<br> Find the value of y.<br> Enter a decimal rounded to the nearest tenth.
il63 [147K]

Answer:

y ≈ 4.3 cm

Step-by-step explanation:

Two secants drawn from outside the circle, then

The product of the external part and the entire secant is equal to the product of the external part and the entire secant of the other secant, that is

3(3 + y) = 2(2 + 6 + 3) ← distribute both sides

9 + 3y = 2 × 11

9 + 3y = 22 ( subtract 9 from both sides )

3y = 13 ( divide booth sides by 3 )

y = 13 ÷ 3 ≈ 4.3 ( to the nearest tenth )
