Answer:
x = 65
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)
x² = 25 × 169 = 4225 ( take square root of both sides )
x =
= 65
Answer:
∠ GDH = 67.5°
Step-by-step explanation:
The measure of the chord- chord angle GDH is half the sum of the measures of the arcs intercepted by the angle and its vertical angle.
∠ GDH =
(GH + EF) =
(90 + 45)° = 0.5 × 135° = 67.5°
Answer:
6x sec2 (x2+5) the number to are in the top of x a c.
Answer:
<h2>
19.596 feet</h2>
Step-by-step explanation:
Use the pythagorean theorem.
a^2 + b^2 = c^2
a = 20ft
c = 28ft
400 + b^2 = 784
b^2 = 384
b = 19.596
