Answer:
Step-by-step explanation:
Let the width be W.
14w=(8*10)
14w=80
The width of the frame needs to be at least 5.7 inches.
Given:
The three exterior angles of a pentagon measures 60,80 and 90.
To find:
The measure of other two exterior angle, assuming them equally.
Solution:
Let x be the measure of two other exterior angles of the pentagon.
We know that the sum of all exterior angles of a pentagon is 360 degrees.




Divide both sides by 2.


Therefore, the measures of both exterior angles are 65 degrees.
Answer:
62
Step-by-step explanation:
90 - 28
complementary angles equal to 90
