Answer:
A
Step-by-step explanation:
First, we need to find the unknown angle of the triangle.
40 + 20 = 60
180 - 60 = 120
So the unknown angle is 120.
Then, we can use the law of sines to create a proportion.
sin(120)/8 = sin(40)/a
Then, we can simplify this.
a is about 5.9, or answer choice A.
The perimeter for each of the problems:
a. 92 ft.
b. 38 cm.
c1. 25x + 5
c2. 55
Hope this helped! :D
10 km
First step: Divide 523.6 by 4/3
Second step: You'll get 392.7 from step one and you'll divide that by Pi.
Third step: you take the cube root of the number that you get from the second step and you'll get 125.
And you end up with 5 km, but it's the diameter so you must multiply by 2
Final answer: 10 km
31/50 you can’t reduce because 31 is prime
