Astudent finished 8 of her homework problems in class. if the ratio of problems she finished to problems she still had left was 4: 1, how many homework problems did she have total?

10 problems

Explanation:

The ratio can be used to find the number of problems left. Then, you can add all the problems together to find your final answer.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
