Answer:
2.24
Step-by-step explanation:
Answer:
Statement 2: ∠BAC = ∠CZY
Reason 3: Vertically opposite angles
Statement 4: YC = CB
Reason 5: AAS (Angle, Angle, Side)
Reason 6: Corresponding sides, congruent triangles
These calculations are based on the drawing of the file enclosed.
There are three right triangles.
From the big right triangle:
a^2 + b^2 = 25^2
From the small right triangle on the left side:
(25-x)^2 + 10^2 = a^2
From the small right triangle on the right side
x^2 +10^2 = b^2
=> (25-x)^2 + 10^2 + x^2 + 10^2 = a^2 + b^2
=> (25-x)^2 + 10^2 + x^2 + 10^2 = 25^2
=> 25^2 - 50x + x^2 + 10^2 + 10^2 = 25^2
=> x^2 -50x + 100 =0
Use the quadratic formular to find the roots:
x = 2.1 and x = 47.9
Distance from back: 25 - 2.1 = 22.9 ft
Answer: 22.9 ft
Recall that

Dividing both sides by cosh²(x) gives

Also, recall the identity

Then

Answer:
x = 24 makes the original equation true
Step-by-step explanation:
2 < x ≤ 24
2 < x signifies x cannot be equal to 2
x≤24 signifies x can be equal to 24.
