Answer:
ABC~WXY by AA
Step-by-step explanation:
In ΔABC
∠B = 90°
∠A = 27°
To Find ∠C
Angle sum property: The sum of all angles of triangle is 180°
∠A+∠B+∠C=180°
27°+90°+∠C=180°
∠C=180°-117°
∠C=63°
In ΔWXY
∠X = 90°
∠Y = 63°
We will use angle sum property
So, ∠W+∠Y+∠X=180°
90°+63°+∠W=180°
∠W=180°-(90°+63°)
∠W=27°
So, ∠A=∠W
∠B =∠X
∠C = ∠Y
So, ABC~WXY by Angle - Angle property.
Hence ABC~WXY by AA

Reduce the expression<span> by cancelling the </span><span>common factors</span><span>.
</span>7<span>a^8</span><span>b^<span>6
</span></span>28a^11 b^7 divided by 4a^3b simplified is 7a^8b^6
5ax+2a=9a
5ax+2a-2a=9a-2a
5ax =7a
5ax/5a =7a/5a
x=7/5
