Two people bought gas. Each gallon of gas cost the same amount. The money that they spent, in dollars, is represented by the exp
e-lub [12.9K]

Answer:

Cost =$3

Amount = 8 gallons and 17 gallons

Step-by-step explanation:

Given

24 + 51

Required

Simplify to show the cost and amount of gas bought by each individual

24 + 51

[Factorize]

3(8 + 17)

The above can't be factored any further.

Since the cost of gas for both individuals is the same, we can conclude the following.

Cost = $3

This is so because it applies to both numbers in brackets

Amount of Gas = 8 gallons and 17 gallons respectively by both individuals

Solve the right triangle​ ABC, with Cequals90degrees. Aequals58.3degrees​, cequals24.8 ft
horsena [70]

m∠B = 31.7° , a = 21.1 ft , b = 13.0 ft

Step-by-step explanation:

If ABC is a right triangle, where the right angle is B, then

  • The hypotenuse of the triangle is b and a , c are its legs
  • sin(A) = \frac{a}{b}
  • sin(C) = \frac{c}{b}
  • b=\sqrt{a^{2}+c^{2}}
  • The sum of the measures of the two acute angles A and C is 90°

∵ ABC is a right triangle

∵ m∠C = 90°

∴ c is the hypotenuse and a , b are its legs

∵ m∠A = 58.3°

- The sum of the two acute angles in the right triangle = 90°

∴ m∠A + m∠B = 90°

- Substitute the measure of angle A

∴ 58.3 + m∠B = 90

- Subtract 58.3 from both sides

∴ m∠B = 31.7°

∵ sin(A) = \frac{a}{c}

∵ c = 24.8 feet

∴ sin(58.3) = \frac{a}{24.8}

- By using cross multiplication

∴ a = (24.8) × sin(58.3)

∴ a = 21.1 ft

∵ sin(B) = \frac{b}{c}

∵ c = 24.8 feet

∴ sin(31.7) = \frac{b}{24.8}

- By using cross multiplication

∴ b = (24.8) × sin(31.7)

∴ b = 13.0 ft

m∠B = 31.7° , a = 21.1 ft , b = 13.0 ft
