decimal form: 2.3
Answer: 25
Assuming the dotted line touches the middle of the base of the triangle,
Using Pythagoras Theorem,
(30/2)^2 + (20)^2 = x^2
x^2 = (15)^2 + 400
x^2 = 625
x = √625 or -(√625)
x = 25 or -25
But since x needs to be a positive value,
x = 25
Answer:
a/ (5r^2) = t
Step-by-step explanation:
a= 5r^2 t
Divide each side by 5r^2
a/ 5r^2 = 5r^2 t/5r^2 t
a/ 5r^2 = t
