Answer:
39 m.
Step-by-step explanation:
The area of a triangle is calculated by the expression given as:
Area = bh/2
where b is the base and h is the height.
We calculate as follows:
270 = b (15) / 2
b = 36
hypotenuse = sqrt ( 15^2 + 36^2 ) = 39

Answer:
2x - 10
Step-by-step explanation:
2(x - 5)
distribute
2*x - 2*5
2x - 2*5
2x - 10
Answer:
9 sides.
Step-by-step explanation:
N is the # of sides.
140 = ((n-2) x 180) / n
Multiply both sides by n
140 n = (n-2) x 180
Distribute the right side
140 n = 180 n - 360
Subtract 140 n and add 360 to both sides.
40 n = 360
n = 9
