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

The measure of angle C for triangle ABC is 75 degrees. Option D is correct.

What is an isosceles triangle?

The triangle in which the two opposite sides are equal and the two opposite angles are equal is called the isosceles triangle.

Since ABC is isosceles, we know that C is equal to B. Therefore, we can add all the angles together and set them 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

Hence, option C is correct.
