Answer:
Ladder reaches 9.76 high.
Step-by-step explanation:
From the figure attached,
Ac is the ladder which reaches at the point A when leans against the side of a house.
Length of the ladder = 10 feet
Distance of the ladder form the base of a house = 2.2 ft
By Pythagoras theorem,
AC² = AB² + BC²
(10)² = h² + (2.2)²
h² = 100 - 4.84
h = √95.16
h = 9.755 feet
≈ 9.76 feet
Therefore, the ladder reaches the 9.76 high.
Answer: 116 degrees.
Step-by-step explanation:
Interior angles of a triangle add to 180.
Knowing the first two angles are 36 and 28, you can subtract them from 180 to find the answer:
180 - 36 - 28 = 116
