If ∠C and ∠D are complementary angles, m∠C = (4x + 3)°, and m∠D = (15x – 8)°, find m∠D

52

Step-by-step explanation:

complementary angles meaning sum of both angles is 90

so equations is

(4x + 3) + (15x – 8) = 90

x=5

insert x into angle d equation

d=15(5)-8

d=60-8

d=52

<D = 67 degrees

Step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
