Answer:
h= 14
Step-by-step explanation:
7h-5(3h-8)= -72 PEDMAS Parenthesis first
7h-15h+40= -72 combine like terms
-8h+40= -72 subtract 40 from both sides
-8h=-112 divide by -8
h=14
Answer:
x = 2.5
Step-by-step explanation:
hypotenuse^2 = side^2 + side^2
(x+4)^2 = x^2 + (6)^2
x^2 + 8x + 16 = x^2 +36
we get,
8x = 36 - 16
x = 20/8
x = 2.5
Answer:
Step-by-step explanation:
Given
Required
Determine:
Solving for , we have:
--- angle on a straight line
So, we have:
To solve for , we have:
--- Vertically opposite angles
So:
All you have to do is find a common denominator (like 6x5) and multiply the 1 in 1/6 by 5 and the 4 in 4/5 by 6 and then do what ever you get the biggest fraction minus the smallest fraction and then you have your answer. Hope that helped.
Answer:
9
Step-by-step explanation:
Use the Pythagorean Theorem which states
a² + b² = c²
then plug in your given terms
a² + 5.6² = 10.6²
find the squares
a² + 31.36 = 112.36
subtract 31.36 from 112.36 to find your a²
a² = 81
then find the square root of 81, which is 9 becuase 9 x 9 is 81
