Question

What is the value of x in the triangle to the right? (7x+3) 85 50

Answer 1

Explanation:

We know that a triangle angles total equals 180 so we could use the numbers and the equation, add it up and then find the value of x

(7x + 3) + 85 + 50 = 180

7x + 138 = 180

7x = 180-138

7x = 42

x = 6

Now that we found the value of x we can know substitute the value into the equation to find the value of the angle.

7x+3

42+3

45
