You can use this to help you. label the triangle like the picture and use the equations. I hope this helps.
Answer:
the unknown angle is 88°
Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the opposite interior angles. Therefore, in the tall triangle, 60 + 40 = 100, meaning the bottom left angle in the small triangle is 100-64=36. And b/c angle sum of a triangle is 180°, 180-36-56=88°
X - the number
3(x+1)=2x+4
3x+3=2x+4
3x-2x=4-3
x=1
AB = 1/2
BC = -2
CD = 1/2
DA = -2
