ranga · Answer

Solve for x first.  The three interior angles of a triangle add to 180. 
Then solve for z.  x + z = 180 (linear pair)
Then solve for y. The three interior angles of a triangle add to 180.

mathstudent55 · Answer

What is the sum of the measures of the angles of a triangle?

anonymous · Answer

180?

mathstudent55 · Answer

Correct.

mathstudent55 · Answer

Look at the triangle on the left side. One angle is 36, one angle is 63, and one angle is x. All three angles added together are 180. What is x?

anonymous · Answer

81?

anonymous · Answer

does x equal 99? 

because what i did to get that was 

63+36+81x=180x
then i subtracted 81 from both sides and got 99 
then i added 63 and 36 and got 99

Can anybody help me?

anonymous · Answer

Nevermind i got help someplace else. But thanks for helping some what :)

mathstudent55 · Answer

63 + 36 + x = 180
99 + x = 180
x = 81

mathstudent55 · Answer

Once you know x, then you can find z.
x and z are called a linear pair.
The sum of their mesures is 180.
We know x is 81.
x + z = 180
81 + z = 180
z = 99

mathstudent55 · Answer

Once you have z, you work on the triangle that has 13, z and y.
13 + z + y = 180
13 + 99 + y = 180
112 + y = 180
y = 68
