The measure of the supplement of an angle is three times the measure of the

gtnhenbr [62]

<h2>Answer:</h2>

<h3><em>x=45degrees</em></h3>

<h2>Step-by-step explanation:</h2>

Let the angle to be solved be x

Let the supplement/compliment by y

x+y=90 Complimentary angles add up to 90 degrees.

x+3y=180 Supplementary angles add up to 180 degrees, the other angle is thrice the other compliment.

Evaluating this as a system:

x+y=90 Isolate x:

x=90−y Input into the other equation:

(90−y)+3y=180 Combine like terms, isolate y and its coefficients:

2y=90 Isolate y

y=45 Input into the first equation:

x+45=90 Isolate x:

x=45degrees

Midsegment of a trapezoid find x

shepuryov [24]

Answer:

x = 7

Step-by-step explanation:

Based on the midsegment theorem of a trapezoid, thus:

NP = (JK + ML)/2

Substitute

45 = (3x + 11 + 10x - 12)/2

2*45 = 13x - 1

90 = 13x - 1

90 + 1 = 13x

91 = 13x

Divide both sides by 13

91/13 = x

7 = x

x = 7
