Answer:
A.) 20
Step-by-step explanation:
These angles are complementary meaning they add up to 90°.
4x - 10 + x = 90
5x - 10 = 90
5x = 100
x = 20
Answer:
AC = 15.588
Step-by-step explanation:
(all rounded to nearest thousandth)
sin(60) = x/18
first solve: sin(60) = 0.866
0.866 = x/18
multiply 18 on both sides
x = 15.588
Answer:
-0.2588 but rounded is -0.26
Step-by-step explanation:
Answer:
Option B that is (2,6) is correct
Explanation:
We have been given with system of equations
and 
Here, we will substitute the value of in
We will get 
Further simplification we will get to 
Hence, the value of 
And now, substituting the value in we will get 
.
Therefore, option B is correct.
