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.
Answer:
Commutative property of multiplcation.
Step-by-step explanation:
An identifier for the property of multiplcation is by multiplying it by 1. Therefore the answer remains the same.
The answer is 28.2 because 479.4 ft. ÷ 17 ft. = 28.2 ft.
15 - 2m = how much she has left.
so 15 minus 2 times the cost per book will tell you how much she has left.
