Answer:
tanI = 
Step-by-step explanation:
We require to calculate GH using Pythagoras' identity in the right triangle.
GH² + GI² = HI²
GH² + 5² = (
)²
GH² + 25 = 95 ( subtract 25 from both sides )
GH² = 70 ( take square root of both sides )
GH = 
Then
tanI =
=
= 
256 is the answer. I know this because 128+128 equals 256.
Answer:
19°
Step-by-step explanation:
<u>Concept</u><u> </u><u>Used </u><u>:</u><u>-</u>
- The measure of a straight line is 180°. So the sum of angles on a straight line is 180° .
Using this ,
<h3>Hence the value of x is 19°</h3>
