Answer:
x° = 67°
Step-by-step explanation:
1. The first three diagrams are showing you that opposite exterior angles are congruent. Based on that, when you are faced with opposite exterior angles in the fourth diagram, you are able to conclude they are congruent. That means x° = 67°.
2. You can determine the other angles in the figure based on linear angles being supplementary, and same-side interior angles being supplementary. After you work through all the angles, you find that x = 67.
39=3m-15
39+15=3m
54=3m
54/3=3m/3
m=18
Answer: isolate the variable by dividing each side by factors that don't contain the variable.
x is less than or equal to 15
Y=4(0-2)^2-1
y=15
(0,15)
plug 0 for x
0=4(x-2)^2-1
(5/2,0) and (3/2,0)
plug 0 for y
Answer:
x=142
Step-by-step explanation:
so x and 142 equal eachother because they are alternate exterior angles!
set up the equation so we can solve for x
x=142
