Answer:
25
Step-by-step explanation:
The perimeter of triangle is equal to the sum of all sides of triangle
then:
5y + (x+8) + (x+3) = 60
5y + 2x +11 = 60
5y +2x = 49 ..............................................................(1)
the hypotenuse - shorter leg = 10
hint ( shorter leg ) = x+3
then
5y - (x + 3 ) = 10
5y - x - 3 = 10
5y - x = 13 .................................................... (2)
from 1 and 2
5y +2x = 49 .................................................................. (3)
5y - x = 13 (multiply both sides by 2 )
10y - 2x = 26 ..................................................................(4)
by sum 3 and 4
15y = 75
then y = 75/15 = 5
then hypotenuse = 5y = 5 x 5 = 25
Answer:
We know the square root of 36 is 6.
As a result, the total value inside the bracket should give us 6.
Thus, 13 - 7 does gives us 6.
So, x = 13
Or
(x – 7)^2 = 36,
Square root both sides to get rid of the square symbol
Now:
(x - 7) = 6
+7 both sides
x= 13
Hope this helps!
