Answer:
x=12
Step-by-step explanation:
The right side is a right triangle
The base is 1/2 of the bottom or 5
The height is x and the hypotenuse is 13
We can use the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +x^2=13^2
25+x^2 = 169
Subtract 25 from each side
25-25+x^2 = 169-26
x^2 =144
Take the square root of each side
sqrt(x^2) = sqrt(144)
x= 12
Answer:
For question 14
The answer is x= 52%
Step-by-step explanation:
Answer:
7 x23 = 161
Step-by-step explanation:
Use pythagorean theory
a^2 + b^2 = c^2
5^2 + 12^2 = 169
square root of 169 is 13
the missing side length is 13 in
Answer:
0.40 x 50
Step-by-step explanation:
40% is of 1 so it can be rewritten as 0.40
