x = 80

Step-by-step explanation:

We know the sum of the angles of a triangle is 180

x+y+z = 180

Since this is an isosceles triangle y=x

x +x + z = 180

We also know that x = 4z

Writing this in terms of x since we want to find angle x    

z = 1/4x

x+x+1/4x = 180

Combine like terms

2x +1/4x = 180

Multiply each side by 4 to get rid of fractions

4(2x +1/4x) = 180*4

8x +x =720

9x = 720

Divide by 9

9x/9 = 720/9

x = 80

C) 80

Step-by-step explanation:

Let the base angles be 4x

Vertex would be x

Total angle in a triangle = 180

x + 4x + 4x = 180

9x = 180

x = 20

4x = 80

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

ok then what happened.
