The answer is 7.5 because you divide the circumference in half. Half of 15 is 7.5.

The circumference is pi times the diameter. The diameter is twice the radius.
Radius=\frac{circumference}{2\pi}=\frac{7.5}{\pi}
The answer is:
\frac{7.5}{\pi}

Help on both <br><br> please !!! <br><br> don't give me irrelevant answers pls
Gennadij [26K]

Answer:

< 1 is 85

X= 50

Step-by-step explanation:

ok the first question has 2 angles given 60 and 65

consider this one shows a 90 degree angle and the other does not. so  60 plus 90 equals 150 degrees

the u must say 65 plus x (x being angle 1) must also equal 150

subtract 65 from 150 and you get 85

now the second problem lets use the

Exterior Angle Theorem

The measure of an exterior angle (our w) of a triangle equals to the sum of the measures of the two remote interior angles (our x and y) of the triangle.

using this we know the 40 degree angle and 2x + 20 equals 3x plus 10

so we subtract 10 degrees from both sides and get

2x plus 10 plus 40 equals 3x now this means x equals 10 plus 40 which is 50
