Answer:

5 hours

Step-by-step explanation:

The equation to solve this is 7.80h+35=74.

7.80 represents the cost per hour, h represents the number of hours, 35 is the reservation fee, and 74 represents the total money.

7.80h+35-35=74-35

7.80h=39

h=5

Find the measure of angle C of a triangle ABC, if: d m∠A = 60°+α, m∠B = 60°−α
snow_lady [41]

Answer:

m∠C  =  60°

Step-by-step explanation:

we know that sum of angles of a traingle is 18 degrees.

given

m∠A = 60°+α,

m∠B = 60°−α

we have to find  m∠C

m∠A + m∠B +  m∠C = 180

60°+α +  60° - α +m∠C = 180

+α and -α gets cancelled

120°+m∠C = 180

=> m∠C  =  180° -  120° =  60°

Thus, measure of angle c is  60°.
