Answer:
True
Step-by-step explanation:
ed 2020. I went back to check the answer so 100% right.
We have a right triangle with
a = one leg = 28
b = other leg = 21
c = hypotenuse = 5x
use the pythagorean theorem (a^2+b^2 = c^2) and solve for x
a^2+b^2 = c^2
28^2+21^2 = (5x)^2
784+441 = 25x^2
1225 = 25x^2
25x^2 = 1225
(25x^2)/25 = 1225/25
x^2 = 49
sqrt(x^2) = sqrt(49)
|x| = 7
x = 7 or x = -7
Since the hypotenuse has length 5x meters, this means
5x = 5*7 = 35
or
5x = 5(-7) = -35
Toss out the negative length as it makes no sense.
The only value of x is x = 7
Therefore the final answer is x = 7

Ok, I shall help.
Please give me brainliest answer.
So first step
25x+8+9x+2=180
We can do this because they are interior angles which add to 180 degrees.
So now we simplify.
25x+9x+2+8=180
34x+10=180
Minus 10 from both sides to get x.
34x = 170
Divide by 34 to only find x.
This leaves x=5 now we find y.
9x+2=7y+5
We can make these two equal because they are alternate angles which are always equal.
Now as we established earlier x is 5 so we substitute.
9(5)+2=7y+5
45+2=7y+5
47=7y+5
Now we minus 5 from both sides to leave 7y
47-5=7y
42=7y
Now we divide by 7 to only get y.
Y=6
X=5
Hope it helps!
Plz give me brainliest answer!
let the unknown answer be equal to f
.-2.1 - f = -3/2
-f = -3/2 + 2.1
-f = 0.6
f = -0.6
