Answer:
a = 33 degrees
Step-by-step explanation:
Note that 57 degrees and Angle a are complementary: they add up to 90 degrees.
Thus, a = 90 degrees less 57 degrees = 33 degrees
I cant really read it that well D:
Subtract the right side and you have
x² -10x -6 -2x -1 = 0
x² -12x -7 = 0
This corresponds to the selection ...
C. x² -12x - 7 = 0
The length of AC is 8
Explanation:
Given that ABC is a right angled triangle.
The measure of angle A is and
<u>Length of AC:</u>
Using the trigonometric ratios, we have,
where and
Substituting the values, we have,
Multiplying both sides of the equation by AC, we get,
Multiplying both sides by , we get,
Simplifying, we get,
Thus, the length of AC is 8
