Answer:
8x+140=180
8x=40
x=5°
Step-by-step explanation:
Sum of angles in a straight line=180°
√120 ≈ 10.95
and 10.95²≈ 120
therefore each side of this square room is about 10.95 feet.
The value of y in the triangle is 6°.
<h3>How to calculate the value of y in the triangle?</h3>
Firstly, it's important to note that a triangle has the total angles of 180°.
Based on the information, the triangle has interior angle measures of 11y, 10y + 10°, and 10y - 16º.
The value of y in the triangle will be illustrated thus:
11y + 10y + 10 + 10y - 16 = 180
31y - 6 = 180
31y = 180 + 6.
31y = 186
Divide.
y = 186 / 31
y = 6
The value of y is 6.
