Answer:
The horizontal line is to the y-axis
If you mean the gradient then it would be -3/2 because if you multiply the 2 together they equal minus 1. That’s how u figure out if 2 lines are perpendicular
Answer:
The measure of the complement is 30°
Step-by-step explanation:
we know that
Two angles are supplementary if their sum is equal to 180 degrees
Two angles are complementary if their sum is equal to 90 degrees
Let
x -----> the measure of an angle
we know that
180°-x=4(90°-x)
Solve for x
180°-x=360°-4x
4x-x=360°-180°
3x=180°
x=60°
Find the complement
90°-x=90°-60°=30°
