Answer:
In triangle AB, A and B are acute angles so. AC and BC are right angles.
Sin A = 10/13
13 is the hypotenuse side and 10 is the opposite side.
To find cos A.
From pythagorean theorem:
Step-by-step explanation:
Answer:The function is a direct variation function with a constant
of variation of 1.5.
Step-by-step explanation:
Step-by-step explanation:
Assuming that the 270° rotation is in a clockwise motion,
A point (a, b) which undergoes such a rotation will have the new point (-b, a).
Since we have A(2, 1),
A' has the coordinates (-1, 2).
75-25=50
50/75= 66.67% decrease
<u>Answer:</u>
The correct answer option is x = -16 and x = 16.
<u>Step-by-step explanation:</u>
We are given the following equation and we are to find the solution for this equation:

For the given equation, involving the modulus, we will have a positive as well as a negative value for it in order to find its solution set.
and 
and
x = -16 and x = 16
