The angles 46 degrees and 44 degrees are complementary. True or False

sin 60 degrees =cos 30 degrees. True or False

In a right triangle, one of the angles is 90 degrees and the sum of the other two angles is 90 degrees. True or False

In a right triangle, if two sides are known, we can solve the triangle. True or False

In a right triangle, if the two acute angles are known, we can solve the triangle. True or False

Help me Please!!!!

1. Complementary angles are angles whose measures add up to 90°.
46° + 44° = 90°, so the angles are complementary. true

2. sin(x) = cos(90-x). Here's why:
Sine = opposite/hypotenuse
Cosine = adjacent/hypotenuse
The side opposite one angle is the same as the side adjacent to the opposite angle.
Therefore sin(angle) = cos(opposite angle)
These can be expressed as (x) and (90-x), as we will explore in question #3.
Anyways, sin(60°) = cos(90-60°) = cos(30°), so this is true

3. If we have a right triangle, it must have one right angle measuring 90°.
The angles of a triangle add up to 180°.
The other two angles' measures must add up to 90° because of this. true

4. true
Use the two sides to find the third (Pythagorean theorem)
Use the Law of Cosines to find each angle.

5. false
We need a side to know how large the triangle is going to be.
This is why triangles that share two angles are similar but not necessarily congruent.
