DE // BC
so AD/AB = AE/AC
The Triangle ADE is similar to triangle ABC
Answer is the first option
Triangle A ≡ Triangle A
Answer:
what problem??
Step-by-step explanation:
S + a = 722
s = 72 + a
(72 + a) + a = 722
2a + 72 = 722
2a = 722 - 72
2a = 650
a = 650/2
a = 325 <== adults
s = 72 + a
s = 72 + 325
s = 397 <== students
Answer:
Step-by-step explanation:
Given:
Length of radius of circle = 5 feets
Length of perpendicular bisector = 4 feets
To find:
Area of the shaded portion of the circle
Solution:
As OD is perpendicular bisector of AB,
Area of = 1/2 (base) × (height) = square feets
Area of sector AOBC = square feets
Here, r denotes radius of circle
So,
Area of shaded portion = Area of sector AOBC - Area of =
