Y=mx+b

b=y-intercept (what y is when x is 0)

b= -7

m=slope

m=change in y divided by change in x

m=(y2-y1)/(x2-x1)

m=(17-5)/(4-2)

m=12/2

m=6

Y=mx+b

Y=4x+(-7)

Y=4x-7

The sum of two complimentary angles is 90. . For one pair of complimentary angles, the measure of the first angle is 15 less tha

soldi70 [24.7K]

Answer:

$x=55 \textdegree$

$y=35 \textdegree$

Step-by-step explanation:

From the question we are told that

Sum of two angle =90

First angle is 15 less than twice the measure of the second angle.

Generally interpreting mathematically we have

Let x be the first angle and second angle y

$x=2y-15$

Therefore

$2y-15 +y=90$

$3y=105$

$y=\frac{105}{3}$

$y=35 \textdegree$

Therefore

$x+35=90$

$x=90-35$

$x=55\textdegree$
