All angles in a triangle add to 180 so

B = 180 - 90 - A
B = 90 - 20.8
B = 69.2

Can find b with tangent of A
tangent is opposite over adjacent.
opposite to A = 20.8 is 11.2 and adjacent is b

tan(20.8) = 11.2 / b
b = 11.2 / tan (20.8)
b = 29.5

c can be found with sine of A

sin(20.8) = 11.2 / c
c = 11.2 / sin(20.8)
c = 31.5

B = 69.2°,  b = 29.5, c = 31.5

8. Aaron and Zelly want to rent a tandem bike so that
ololo11 [35]

Answer:

80 = 18.50h + 6

Step-by-step explanation:

Given

Amount = \$80

Rent = \$18.50 per hour

Helmet = \$3.0

Individuals =2

Required

Derive an expression for the scenario

A tandem bike allows 2 individuals to ride on it at a time.

So, they will only pay for one rental fee because both can ride on it at the same time.

However, they need to get separate helmets.

For Helmets, they will spend:

\$3 * 2 =\$ 6

For Rental, they will spend

\$18.50 * h = \$18.50h for h hours.

Total = Rentals + Helmets

Total = 18.50h + 6

Recall that they have just $80 to spend

So, substitute 80 for total

80 = 18.50h + 6

Hence, option C answers the question.
