ASAP please!!! Triangle ABC has angle measures as shown show work.complete sentence
a. What is the value of x?
b. What is the measure of angle CAB?
d. When these 3 interior angles of a triangle are added together, what does it equal?

Step-by-step explanation:

The interior angles of a triangle add up to 180 degrees.

a.

90 + 2x + (3x - 20) = 180

90 + 2x + 3x - 20 = 180

70 + 5x = 180

5x = 110

x = 22

b.

2(22) = 44

c.

The interior angles of a triangle add up to 180 degrees.

please give me a brainliest answer

18.84

Step-by-step explanation:

The equation for circumference is C=2πr

Plug in the numbers and the equation should be 2π3

2 times 3.14 is 6.28

6.28 times 3 is 18.84

Your answer will be 18.84

Hope this helps :)
