The Answer is 5
Knowing that there are 180* in a triangle we would add up 75 + 90 and get 165. Which leaves 15* left over. Which would mean 3(5)* = 15*.
75 + 90 + 15 = 180

Answer:

x=5

Step-by-step explanation:

A triangle has a total of 180° in angles.

Subtract values of the known angles:

180-75-90=15

15=3x°

Then cancel out the 3 by dividing 15 by 3.

15/3=5

so, x=5

I really hope this helps! :)
