In this situation you would use cos
which is adjacent over hypotenuse
so I take the cos50 and have it equal to 17 / x
cos(50)= 17/x
which is the same as ...
17 divided by cos(50) =x
x=26.44730506
which rounds to 26.45
So your answer would be A)
I hope everything makes sense, enjoy! <span />
Answer:
.3
Step-by-step explanation:
From given picture we can see that X is mid point of line PQ
So PQ=2PX
From given picture we can see that Y is mid point of line PR
So PR=2PY
Now consider triangles PRQ and PYX
Sides PQ and PX has same ratio as of sides PR and PY (as calculated above)
angle XPY= angle QPR (common angle)
Hence triangles PRQ and PYX are similar.
We know that ratio of the sides of similar triangles is always equal so we can write:

Plug the given values QR=8 and PQ=2PX





Hence final answer is XY = 4 units.
Y = 180 - 51 -56 = 73
x = 180 - 73 - 72 = 35
x = 35 degrees
