Answer:
x=3
Step-by-step explanation:
(11-3)+3x+1 = 5x+3
8+3x+1 = 5x+3
9+3x= 5x+3
6=2x
a = 50
From the introduction, you know that the area is 3a^2
You also know that it is 7500 square feet. \
So the two must be equal
3a^2 = 7500 Divide by 3
a^2 = 7500/3
a^2 = 2500
The square root of 2500 is 50
sqrt(a^2) = sqrt(2500)
4/5
sine is opposite over hypotenuse,
so it's 40/50=4/5
Solution given:
here
by using Pythagoras law
hypotenuse =
Cos C=
Answer: 0 (zero)
