Answer:
x = 78°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
110° is an exterior angle of the triangle on the right , then
x + 32°= 110° ( subtract 32° from both sides )
measure of sum interior angle = (n-2)180 where n is the no. of sides
=(3-2)180
=180°
The first triangle :
110+45+y = 180
155+y = 180
y = 180-155
y = 25°
The whole triangle :
45+57+x = 180
102+x = 180
x = 180-102
(4,5)
-6 I meant
(-3 ,-4)
I have made it in above picture
hope it helps
There are 16 squares and 12/16 is 75 percent so 75% - green
25% - white hope this helps :)
