Answer:
Troy is 9.4 miles from his starting point.
Step-by-step explanation:
Using the Pythagorean theorem, we can calculate the straight distance from his start to end point, which would be the hypotenuse. 8 miles due east will be the first leg, A, and 5 miles due north will be the second leg, B. A(8) squared plus B(5) squared = C squared. C would equal 9.43, rounded to the nearest tenth is 9.4
Answer: 4 / 5
Step-by-step explanation: 1) For a right triangle, the ratio sine is defined as:
sin(x) = opposite-leg / hypotenuse
2) x is the angle. In this case: A
3) As per the figure, the opposite leg to tha angle A measures 28
4) As per the figure, the hypotenuse measures 35
5) Calculations:
sin(A) = 28 / 35
Simplify dividing both numerator and denominator by 7 => 28/35 = 4/5
Answer:
1936
Step-by-step explanation:
x² + 87 = (x +1)²
x² + 1)² - x² =87
(x² + 2x +1) = 87
2x + 1 = 87 ⇒ x = 44
44² = 1936
So they go up and first they double then triple etc do the answer would be 3050
