Question

Triangle ABC has angle measures as shown below. Using the information in the

diagram, find the value of x. Be sure to write your answer down on a piece of paper -
you will need it for Question 4.
In your answer, give the value of x and explain how you calculated it.
3(x + 2)°
35
52°
0

Answer 1

x=29 i know because i put that and it was a 100

Answer 2

35 + 52 + 3(x + 2) = 180
87 + 3x + 6 = 180 ( add the like terms and use distributive property)
93 + 3x = 180
-93 -93
3x = 87
÷3 ÷3
x = 29
( the sum of all triangle angles is 180)
