M∠a=(48−x)°m∠b=(9x−38)°m∠c=90°

The question does not specify the condition that must satisfy the given angles. We assume they are the internal angles of a triangle.

x = 10

Step-by-step explanation:

Internal Angles of a Triangle

The measure of the angles of a triangle are given as 48-x, 9x-38, and 90. Since the sum of the internal angles of a triangle is 180°:

48 - x + 9x - 38 + 90 = 180

Simplifying:

100 + 8x = 180

Subtracting 100:

8x = 180 - 100 = 80

x = 80/8

x = 10

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
