Answer:
x = 133°
Step-by-step explanation:
Straight-line pair - A pair of angles that lie on a straight line.
<em>*</em><u><em>Property</em><em>*</em></u>
The sum of two angles of a straight-line pair is equal to <u>180°</u>.
The given angles – x and y – form a <u>straight-line pair.</u>
==> x + y = 180
<em>{</em><em>y</em><em> </em><em>=</em><em> </em><em>4</em><em>7</em><em>°</em><em> </em><em>(</em><em>given</em><em> </em><em>in</em><em> </em><em>t</em><em>he</em><em> </em><em>question</em><em>)</em><em>}</em>
<em>Substituting</em><em> </em><em>4</em><em>7</em><em> </em><em>for</em><em> </em><em>y</em><em>:</em>
==> x + 47 = 180
<em>Subtracting</em><em> </em><em>4</em><em>7</em><em> </em><em>from</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
==> x = 47 - 47 = 180 - 47
==><u> x = 133</u>
Answer:
W = 14, L = 18
Step-by-step explanation:
If L = length and W = width, then:
252 = LW
L = W + 4
Substituting:
252 = (W + 4) W
252 = W² + 4W
0 = W² + 4W − 252
0 = (W + 18) (W − 14)
W = -18 or 14
Since W > 0, W = 14. Which means L = 18.
ANSWER
EXPLANATION
We were given that,
This implies that,
We use the Pythagorean identity
to get,
We were also given that,
This means that,
This is because,
This angles are in the first quadrant so we pick the positive values.
The correct answer is D
