Find the measures of the indicated angles pictures included!!!

25

Step-by-step explanation:

The angles b and 65 are complementary, meaning they sum to 90 degrees. You know this because those 2 angles and the right angle are sitting on a straight line. So, together they equal 180 and 180-90 is 90. Therefore, angle b+65 must equal 90. So, simply subtract 65 from 90 to get the answer, 25.

15.7 cm

Is it a right triangle?

If so we can use Pythagorean Therom:

a^2+b^2=c^2

Solve for c by plugging in a and b

You get c≈6.529931

Perimeter is the sun of all of the sides so just add em together:

6.5+5+4.2= 15.7 cm
