Answer:

C. y=3/2 x + 12

Step-by-step explanation:

lets find slope,

fr that first lets point out some coordinates passing the line: ( 0, 12 ), ( 2,15 )

now find slope using the equation : y -y1/ x - x1

                                                         = 15 - 12 / 2 -0 = 3/2

  • use any coordinates now to find the equation of line using formula:

y - y1 = m ( x - x1 )

y - 12 = 3/2 ( x - 0 )

y -12 = 3/2 x - 0

<em>y =</em> 3/2 x + 12

Therefore, y = 3/2 x + 12 is the equation of the line.

What are the missing angle measures in triangle ABC?
Finger [1]

we know that

In the right triangle ABC

∠A+∠B=90 ------> by complementary angles

so

Step 1

Find the measure of angle B

we know that

tan\  B=\frac{opposite\  side\  angle\  B}{adjacent\  side\  angle\  B}

in this problem

opposite\  side\  angle\  B=7in\\ adjacent\  side\  angle\  B=5in

so

tan\  B=\frac{7}{5} \\ \\ B=arc\ tan\frac{7}{5} \\ \\ B=54.5\ degrees

Step 2

Find the measure of angle A

A+B=90\\ A=90-B\\ A=90-54.5\\ A=35.5\ degrees

therefore

the answer is the option

35.5° and 54.5°
