Answer:
x = 10.3 in
Step-by-step explanation:
To find the value of a, use the area formula for a triangle. The formula is A = 1/2 *b*h. Here b = x and h= x. The formula becomes A = 1/2 *x². Substitute A = 53 and solve for x by using inverse operations.
A = 1/2x²
53 = 1/2x²
106 = x²
√106 = x
10.3 = x
You are asked to find the missing value in
... 40 + ? = 70
given that it is also the solution to
... ? + 5 = 35
Either way, you subtract the constant that is on the same side of the equation as the unknown.
... 40 + ? - 40 = 70 - 40
... ? = 30 . . . . the missing value
_____
You can check to see if this also satisfies the equation
... 30 + 5 = 35 . . . . . . . true
