Answer:
(Square, Right Triangle)
18 meters²
Step-by-step explanation:
You can divide the shape into a square and right triangle, see the attachment :)
The area of the square is the length times the width. So,
3 · 3 = 9
The area of the square is 9 m².
The triangle's area is the base times the height divided by 2. So,
6 · 3 = 18
18 / 2 = 9
The triangle has an area of 9 m².
Add these together.
9 + 9 = 18
The area is 18 meters².
Answer:
A
Step-by-step explanation:
We require to find ∠ A
Subtract the sum of the given angles from 180
∠ A = 180° - (85 + 53)° = 180° - 138° = 42°
Using the Sine rule in Δ ABC, that is
=
, that is
=
( cross- multiply )
AC × sin42° = 85 × sin85° ( divide both sides by sin42° )
AC = ≈ 126.6
