Answer:
I dont know the answer but I found out how you figure out if lines are supplementary
Step-by-step explanation:
1) let the measure of one of the supplementary angles be a
2) measure of the other angle is 2 times a
3) so the measure of the angle is 2a
4) if the sum of the two angles is 180 degrees then the angles are supplementary
C
A triangle is 180 degrees so 120+40 is 160
180-160=20
Question 1)
Given
The expression is 5xy
To determine
Find the value of 5xy if x = 2 and y = 3
5xy
substitute x = 2 and y = 3
5xy = 5(2)(3)
= 5(6)
= 30
Therefore, the value of 5xy = 30 if x = 2 and y = 3.
