Answer:
x= 45
Step-by-step explanation:
The square red square in the bottom left corner of the triangle signifies a 90 degree angle or a "right angle". Since a triangle is 180 degrees in total and we know that both of the x values are equal we can subtract 90 from 180. That leaves us with 90 and since there are two x's we divide by 2 which gives us 45. you can fill in the blanks, each x equals 45 and the corner equals 90. When you add them all up, you should get 180.
