Answer:
option a is correct.
Step-by-step explanation:
We have given the equation:

Squaring both sides of the above equation we get:

After simplifying the first step



After final simplification we get:

We are getting quadratic equation since, the degree in resultant is 2.
Therefore, option a is correct.
Use sin(45)= 5sqrt2/x
Then you would multiply x to sin(45) then divide sin(45) by 5sqrt2
and you would get
10 for M
You would then use Pythagorean theorem and get
3sqrt 10

Step-by-step explanation:
here's the solution,
in the given figure , sum of all angles formed with O measures 360°
because, it forms a complete angle
so,
=》mPOQ + mQOR + mROS + mSOT + mTOP = 360°
=》mPOQ + mQOR + mROS + mSOT + mTOP = (90° × 4)
=》mPOQ + mQOR + mROS + mSOT + mTOP = 4 × right angle
(cuz.. right angle = 90°)
Y = 10
x = -1
u might need to check it again
just to make sure
