Answer:

45/51

Step-by-step explanation:

SOH CAH TOA

Sin x = Opposite/hyp

Cos x = Adjacent/hyp

Tan x = Opposite/Adjac

Here we're looking for Sin R, so we want to find opposite side over the hypotenuse.

Thus, $sin R = \frac{45}{51}$

Which statement is true about vertical angles. 1 point Vertical angles are congruent if two lines are parallel. If vertical angl

Answer:

Vertical angles are always congruent.

Step-by-step explanation:

Vertical angles are formed when two straight lines intersect each other, thereby forming two pairs of opposite angles, which are called vertical angles. Thus, a pair of these vertical angles formed are congruent to each other. So therefore, if two angles are said to be vertical angles, it follows that they are congruent to each other.

Using the diagram attached below, we can see two straight lines intersecting each other to form two pairs of vertical angles:

<a and <b,

<c and <d.

Thus, <a is congruent to <b, and <c is congruent to <d.

Therefore, the standby that is true about vertical angles is that:

Vertical angles are always congruent.
