Answer:
Step-by-step explanation:
The picture of the question in the attached figure
step 1
Find the measure of angle XWV
we know that
The triangle VWX is an isosceles triangle, because has two equal sides (VX=VW)
we have
so
Remember that an isosceles triangle has two equal interior angles
so
step 2
Find the measure of angle WVX
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
substitute the given values
step 3
Find the measure of arc WUX
we know that
----> by central angle
we have
therefore
Answer:
Solve for x:
56 x^2 + 4 = 77
Subtract 4 from both sides:
56 x^2 = 73
Divide both sides by 56:
x^2 = 73/56
Take the square root of both sides:
Answer: |
| x = sqrt(73/14)/2 or x = -sqrt(73/14)/2
