Alright, lets get started.
Last year, Ronnie's utility expenses were = 1935.67 $
After switching to electric water heater to solar water heater, his yearly utility bills get reduced.
This year, Ronnie's utility expenses are = 862.40 $
So the difference on utility bills Ronnie saved =
so, difference Ronnie saved = 1073.27 $
So, the percentage of amount Ronnie saved =
Percentage of amount Ronnie saved = 55.45 %
Hence, 55.45 % Ronnie save on his utlility bills by switching to a solar water heater. : Answer

Answer:
∠A = 26°
Explanation:
If two angles of a triangle have measures equal to the measures of two angles of another triangle, then the triangles are similar. In case of similar triangle, corresponding angles are congruent.
Angle ∠C = 76
So, ∠T = 76 because of corresponding angle.
Given that,
m∠S=3(m∠A)
We know that,
∠S ≅ ∠B
That means ∠B = 3 (∠A)
Sum of angles in a triangle = 180°
∠A + ∠B + ∠C = 180°
∠A + 3∠A + 76° = 180°
4∠A = 180° - 76°
4∠A = 104°
∠A =
∠A = 26°
Final answer.
