Answer:
Option (4)
Step-by-step explanation:
Vertical angles theorem;
"Two vertically opposite angles formed by the intersection of two straight lines are congruent"
By this theorem,
If ∠1 and ∠2 are the vertical angles Given
∠1 ≅ ∠2 Vertical angles theorem
Therefore, Option (4) is the correct option.
Answer:
B
Step-by-step explanation:
Divide 132 by 8. You will get the quotient of 16 and the remainder of 4. So each row has 16 projects. The remaining 4 projects cannot be filled completely in a row.
Supplementary means the 2 angles add up to 180 so...
124+(2x+4)=180
124+2x+4=180
124+2x+4-4=180-4
124+2x=176
124-124+2x=176-124
2x=52
2x/2=52/2
x=26
plug in and check
124+2x+4=180
124+2 (26)+4=180
124+52+4=180
176+4=180
180=180
That would be a right angle
