Question

What is the value of x?



Enter your answer in the box.

Answer 1

Answer:

x = 21

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the given angles and equate to 180, that is

x -4 + 3x + 100 = 180, that is

4x + 96 = 180 ( subtract 96 from both sides )

4x = 84 ( divide both sides by 4 )

x = 21

Answer 2

Yo sup??

by angle sum property of triangle we can say that

x-4+100+3x=180

4x=84

x=21

Hope this helps
