Answer:

Step-by-step explanation: add 15, 25 and 39

then subtract by 180

Answer:

101

Step-by-step explanation:

(There is a shorter way to solve this, is in the other answer omg sorry)

First we have to find the last angle of the smallest triangle.

The addition of all angles in a triangle is always 180º so that means:

39 + 25 + y = 180

y = 180 - 64

y = 116

Now that we know the value of that angle we can find the other angle (not x) and with it we can get the answer.

Because flat angles are 180º too

Then:

116 + z = 180

z = 180 - 116 = 64

Finally now we calculate the addition of all angles again to find x:

x + 15 + 64 = 180

x = 180 - 79

x = 101

Hope it was helpful ;)
