We are given that
In right triangle ABC, if angle A is 90 degrees, angle C is 34 degrees, and AC is 71.4, find BC.
Solution
We will first draw a diagram to illustrate the information
Above we want to find x
The method to use is SOHCAH
From the right angle triangle above we have above, we have the adjacent side and we want to find the hypotenus, so we use cosine
i.e

We need to solve for x here

Thus, |BC| = 86.1 (to the nearest tenth
Answer: The answer is 3.0?s
Step-by-step explanation:
Answer:
If they work together, it would take them 22 hours.
Answer
A. 129.3
B. The students ages can be any number within the ranges, so having the middle number wont represent the other possible heights.
Step by step
'h' is the number between the surrounding number, the first would be 122.
You need to multiply the hight by frequency of each one,
122x7 =854
126x8=1008
130x13=1690
134x9=1206
138x3=414
Add them up = 5172
5172/40 =129.3
Answer:
53%
Step-by-step explanation:
use formula: (new value - original value) / original value and you will get .533 which rounds to 53%
