Question

Triangle ABC is isosceles what is the measure of angle C ? 25 , 30, 60, 75

Answer 1

Answer:

The measure of C is 75 degrees

Step-by-step explanation:

Since ABC is isosceles, we know that C is equal to B. Therefore, we can add all the angles together and set equal to 180 to find the value of x.

A + B + C = 180

x + 5 + 3x + 3x = 180

7x + 5 = 180

7x = 175

x = 25

Now we can plug in the value of x into 3x to find C.

C = 3x

C = 3(25)

C = 75
