Answer:
Step-by-step explanation:
we know that
A 
right triangle has two equal legs
Let
x-----> the length side of the leg of the triangle
y------> the length side of the hypotenuse
so
in this problem we have
substitute the value of y and solve for x
Answer:
x=2
Step-by-step explanation:
x+(2x)^2=18
Answer:
3 tickets
Step-by-step explanation:
The angles ∠CFE and ∠AFB are vertically opposite angles. Then the value of x will be 6.
<h3>What is an angle?</h3>
Angle is the space between the line or the surface that meets. And the angle is measured in degree. For complete 1 rotation, the angle is 360 degrees.
Vertically opposite angle - When two lines intersect, then their opposite angles are equal.
We know that the angle ∠DFE is 90°.
Then the sum of the angle ∠CFD and ∠DFE will be
∠CFD + ∠DFE = 27° + 90°
∠CFD + ∠DFE = 117°
Then the angles ∠CFE and ∠AFB are vertically opposite angles. Then we have
∠CFD = ∠DFE
Put the values
21x - 9 = 117
21x = 126
x = 6
