The sum of the interior angles of<span> a </span>triangle<span> are equal to 180</span>o<span>. To </span>find the third angle of a triangle<span> when the other two </span>angles<span> are known subtract the number of degrees in the other two </span>angles<span> from 180</span><span>o</span>
The measure of the interior angle at vertex C is D. 144.
<h3>How to calculate the angle?</h3>
Based on the information given, the angle will be calculated thus:
8x + 8x + 8x + 3x + 3x = (5 - 2) × 180
30x = 540
Divide both side by 30
30x/30 = 540/30
x = 18
Therefore, at vertex C, we have 8x. This will be:
= 8x
= 8 × 18
= 144

Answer:
g = h/f - d/f
Step-by-step explanation:
It would be 6+4, which equals 10. Then, subtract 104 ft minus 10 to get 94 ft in depth.
