Answer:
B
Step-by-step explanation:
2/5 (10x + 15) = 26
Distribute the 2/5
4x + 6 = 26
4x = 20
x = 5
The racer take 4 hours (between 8:00 to 12:00) to race 3/4 of 6 miles
3/4 of 6 miles = 18/4 = 4.5 miles
4 hours ⇒ 4.5 miles
1 hour ⇒ 4.5 ÷ 4 = 1.125 miles
The time taken to complete 6 miles = 6 ÷ 1.125 = 16/3 hours = 5.3 hours
Answer:
that looks to be a 45 degree angle but I'm not sure
SinB = 8/17
The sin of an angle is equal to opposite/hypotenuse
Use Pythagorean’s Theorem to solve for the opposite side

The opposite side is equal to 8
So sinB = 8/17
