Answer:
= -2x
Step-by-step explanation:
3x and -5x are like terms and -10 and 10 are also like terms. like terms can be added together
= -2x cause the 10's cancel out
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:
6,307 I'm pretty sure
Step-by-step explanation:
Idk really know the step by step but I just subtracted 205 by 199 and 048 by 355
The answer would be:
c) 2^2
