A triangle has a base of 10 cm its other sides are both 13cm long calculate the area
2 answers:
Answer: 60cm^2
Explanation:
Since both sides are 13cm it tells us that it is an isosceles triangle.
And we can find the height by using Pythagorean’s theorem.
If we cut the isosceles triangle into 2 same right triangles, we can take one of the right triangle and we can work out the height.

Answer:
(x) =
x + 8
Step-by-step explanation:
let y = f(x) and rearrange making x the subject, that is
y = 9(x - 8) ← divide both sides by 9
= x - 8 ( add 8 to both sides )
+ 8 = x
Change y back into terms of x with x = (x) , thus
(x) =
x + 8
