Answer:
Because tan represents from θ (theta), the equation should be
=
. Let's leave this equation like that. Now, we need to find the unknown side length, x. We need to use Pythagorean Theorem, because we're given the other two side lengths. The equation should be
. X should equal ±8 or 8, because a side length can't be a negative value. Now, we can plug in 8 into the equation to get
.
Answer:
(1) 9
(2)
(3) 6()
Step-by-step explanation:
From the question,
(1) ()²
Applyin the law of multiplication of surds
()² = (
(2) ()× (
) =
Also applying the the law of multiplication of surd
()×(
) = (
) ( This is an irational answer)
∴ ()×(
) =
(3) 2()×3(
)
Also applying the law of multiplication of surds i.e Multiply surds to surds and whole number to whole number
= 2×3×()×(
)
6×() = 6(
