<u><em>Step-by-step explanation:</em></u>
- Since the triangle is right use the tangent ratio to solve for x

- Multiply both sides by
x ×
( divide both sides by
)
x = ≈ ( nearest tenth )
Answer: D
Step-by-step explanation:
There are two pairs of congruent angles.
Answer:
Step-by-step explanation:
C= 2 *3.14*r
we have diameter 2r=d=18
C=18*3.14
C=56.52
So than there are
1x -5y =15
-1x +5y = -15
--------------------assuming term by term we get
0 0 = 0
so from what result that this system has infinitely many solutions
