Answer:
84
Step-by-step explanation:
A= 1/2• bh
A= 1/2•24(7)
A!! Yes, because adjacent sides aren’t perpendicular
Answer:
see explanation
Step-by-step explanation:
Given
tan a = 
= 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h = 
= 41 , thus
sin a = 
= 
cos a = 
= 
To solve this problem you must apply the proccedure shown below:
1. You have the following information given in the problem above:
- The<span> rectangular deck has the following dimensions: 12 ft by 14 ft.
- When the length and width are increased by the same amount, the area becomes 288 ft</span>².
2. Therefore, you have:
A=bxh
288=(12x)(14x)
288=168x²
3. When you clear the x, you obtain:
x=√288/168
x=(2√21)/7≈1.31
