Answer:
1. A = 59
2. A = 43
Step-by-step explanation:
If we have a right triangle we can use sin, cos and tan.
sin = opp/ hypotenuse
cos= adjacent/ hypotenuse
tan = opposite/ adjacent
For the first problem, we know the opposite and adjacent sides to angle A
tan A = opposite/ adjacent
tan A = 8.8 / 5.2
Take the inverse of each side
tan ^-1 tan A = tan ^-1 (8.8/5.2)
A = 59.42077313
To the nearest degree
A = 59 degrees
For the second problem, we know the adjacent side and the hypotenuse to angle A
cos A = adjacent/hypotenuse
cos A = 15.3/21
Take the inverse of each side
cos ^-1 cos A = cos ^-1 (15.3/21)
A = 43.23323481
To the nearest degree
A = 43 degrees

I took a test with a question like that
Step-by-step explanation:
-3x < 20.3-5
3x > -15.3
x > -5.1
Answer:
Step-by-step explanation:
First, we need to make the demoninators the same so we times 4 by 5 and whatever we do to the bottom, we do to the top, and 5 by 4.
demoninator now doesn't change unless you're multiplying or dividing.
Use the Pythagorean Theorem.
The length of the path is d, and it is the hypotenuse of the right triangle.
50^2 + 120^2 = d^2
2500 + 14400 = d^2
d^2 = 16900
d = 130
Answer: 130 m
