Find the slope first: 4=x 2=y 1=x2 -7=y2
-7-2/1-4=-9/-3
So the slope is -9/-3
so far we have y=-9/-3x-b
then we replace
2=-9/-3(4)-b
2=-9/-3*4-b
2=12-b
12-2=10
10=b
So y=3x-10

If ∠ROQ and ∠ROS are complementary angles, then what is the value of x and m∠ROS?
Colt1911 [192]

Answer:

B. x = 31; m∠ROS = 62°

Step-by-step explanation:

Complementary angles add to 90

∠ROQ + ∠ROS = 90

28+2x = 90

Subtract 28 from each side

2x = 90-28

2x=62

Divide by 2

2x/2 = 62/2

x = 31

∠ROQ =28

∠ROS = 2x=2*31 = 62
