Step-by-step explanation:
Answer: the area of the triangle is 23.4 cm²
Step-by-step explanation:
The given triangle is not a right angle triangle. Since two sides and one angle are known, we can either apply the Heron's formula or the Sine formula which is expressed as
Area of triangle = 1/2abSinC
Where a and b are the sides of the triangle and C is the given angle. Therefore,
Area = 1/2 × 8.2 × 6.4 × Sin63
Area = 1/2 × 8.2 × 6.4 × 0.8910
Area = 23.4 cm² to the nearest tenth.
Since the shower block is in the form of a rectangle. The shower block has an area of 144
. It has a length of 24m. We need to calculate the width of the shower block.
Area of rectangular shower block = length
width
144
= 24 m
width
width = 
width = 6m
So, the width of the shower block is 6 meters.
Angles a and e! they’re alternate interior angles, therefore they are congruent.
Answer: 4.2625
Step-by-step explanation:
11/320=x/124
11*124=320x
1364=320x
x=4.2625
