Answer:
Step-by-step explanation:
-4 ¹/7 + 8 ⅜
-(4 + ¹/7) + 8 + ⅜
-4 - ¹/7 + 8 + ⅜
(-4 + 8) + (-¹/7 + ⅜)
4 + 13/56
We know that AXB + CYD and AXB + FZE = 90
20 + CYD = 90 and 20 + FZE = 90
We can see that CYD and FZE are equal so we can use one equation
Let's use 20 + CYD = 90
CYD = 70 and FZE is also equal to 70 because CYD and FZE are equal.
so 70 + 70 = 140 degree
