Step-by-step explanation:
<u><em>The picture of the question in the attached figure</em></u>
we know that
The height of an isosceles triangle divide the triangle into two congruent right triangles.
so
Applying the Pythagorean Theorem

solve for x




Answer:
The probability that a Tech High student fails math is 0.1006
Step-by-step explanation:
21% students are taking class with Mary.
Every year 4% of Mary’s students fail,
15% students are taking class with Tom
Every year 6% of Tom’s students fail.
64% students are taking class with Alex
Every year 13% of Alex's students fail.
Now we are supposed to find the probability that a Tech High student fails math.



Hence the probability that a Tech High student fails math is 0.1006
The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known. The value of x is 117.8°. thus, the correct option is A.
<h3>What is the Law of Cosine?</h3>
The law of cosine helps us to know the third side of a triangle when two sides of the triangle are already known the angle opposite to the third side is given. It is given by the formula,

where
c is the third side of the triangle
a and b are the other two sides of the triangle,
and θ is the angle opposite to the third side, therefore, opposite to side c.
As per the law of cosine, the measure of angle x can be written as,

Hence, the value of x is 117.8°. thus, the correct option is A.
