Answer:
30°, 60°
Step-by-step explanation:
Let x represent the measure of the smaller angle in degrees. Then the larger unknown angle is 2x, and the sum of the angles in the triangle is 180°:
x + 2x + 90° = 180° . . . the sum of the angles in the triangle
3x = 90° . . . . . . . . . . . . subtract 90°, collect terms
x = 30° . . . . . . . . . . . . . divide by 3; this is the smaller angle
2x = 60° . . . . . . . . . . . .this is the larger angle
The two angles that are not the right angle are 30° and 60°.

Answer: 24
I could be wrong but I believe it’s 24
Answer:

Step-by-step explanation:
we want to solve the following trigonometric equation:

The first step of solving trigonometric equation is to rewrite the equation in terms of one trigonometric function . With Pythagorean theorem, we know that sin²x=1-cos²x . It will be helpful to rewrite the equation in terms of one trig functions. Therefore, substitute 1-cos²
in the place of sin²
:

simplify:

Consider cos²
x. Thus,

solving the quadratic equation yields:

back-substitute:

take inverse trig in both sides

In conclusion,
