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
First : -(-6) will turn into a positive 6
second: -8+6 which equals -2
Answer:
2
Step-by-step explanation:
algebra and bisector means its half
2x + 8 = 50
Subtract 8 from both sides
2x = 42
Divide both by 2
x = 21
The other number could be any number that isn't an even number. For instance: 1,3,5,7,9,11,13,15,17... (you get it)
