The area of the triangle is 26 feet's squared.
<h3 /><h3>How to find the area of a triangle?</h3>area of a triangle = 1 / 2 bh
where
- b = base
- h = height
Therefore,
height = 4 ft
base = 13 ft
Therefore,
area of a triangle = 1 / 2 × 13 × 4
area of a triangle = 52 / 2
area of a triangle = 26 ft²

Answer:
Option (D). 110°
Step-by-step explanation:
Since EB and AD are diameter,
=
= 180°
= 180° -------(1)
And
180° = 40° +
= 140°
Since,
= 140° [Given
]
= 70°
From equation (1),
= 180° -
= 180°- 70°
Therefore, measure of arc(EDC) = 110°
Option (D) will be the answer.
