A parallelogram has one angle that measures 93°. What are the measures of the other three angles in the parallelogram?
2 answers:
Answer: 93, 87 and 87
Explanation:
The given angle is 93 degrees. The angle opposite this is also 93 degrees. Opposite angles of any parallelogram are always the same measure.
Another rule to keep in mind is that: any two adjacent angles add to 180
So if x is adjacent to 93, then 93+x = 180 solves to x = 87. The other two angles, opposite one another, are 87 degrees each.

Answer:
A
Step-by-step explanation:
Given
= 8 + 4A
Multiply through by 3 to clear the fraction
2A = 24 + 12A ( subtract 12A from both sides )
- 10A = 24 ( divide both sides by - 10 )
A = - 2.4 → A
