Answer:
∠a = 45°
Step-by-step explanation:
We are told that △abc and △xyz are congruent.
Thus;
∠a = ∠x
∠b = ∠y
∠c = ∠z
We are given;
∠y = 90°
Thus, ∠b = 90°
Now,we are told that ∠a is one half the size of ∠b.
Thus; ∠a = ½ × ∠b
∠a = ½ × 90
∠a = 45°
let's recall that a square has four equal sides, so if one side is x + 4½ long, then all four are x + 4½ long, and the perimeter is simply the sum of all four.
let's first off, convert the mixed fraction to improper fraction.
