Given:
In Right Angle Triangle GIH
∠ I = 90°
GI = 7 ....Side opposite to angle H
GH = 10 .... Hypotenuse
To Find:
m∠H = ?
Solution:
In Right Angle Triangle ABC ,Sine Identity,

Substituting the values we get;

Now taking
we get;

rounding to nearest tenth we get.
.
Hence
.
The values of x and y are 0.2 and 0.4 respectively.
<em><u>Explanation</u></em>
The given proportions are.....
and 
From the second proportion, we will get....

Now, we will plug this
into the first proportion. So we will get....

So, the values of x and y are 0.2 and 0.4 respectively.
