The answer is C) m∠1 + m∠2 = 90
Explanation: So ∠1 is x and ∠2 is x-4
Basically you know than ∠3 is 90° ... And a straight line is 180° ..                            So technically we can just find out 180-90 is 90(the other angle 1 + 2).
To get 90° we'll add ∠1 and ∠2 in other ways, like technical thinking-
So you already know adding ∠1 and ∠2 is 90°. So ∠1 + ∠2 = 90°
In other words you can say m∠1 + m∠2 = 90

Answer:
The area is 6.25 times greater.
Step-by-step explanation:
Each side of the triangle of the dilated triangle will be 2.5 times the length of the original sides.
The area will increase to 2.5^2 = 6.25 times.
