Answer:
Step-by-step explanation:
Given:
In Δ ABC
m∠C= 90°
For the triangle ABC we can apply trigonometric ratio to find m∠A.
We have:
Substituting values of side BC and AC
Taking inverse tan to get m∠A.
∴
AB can be found out using Pythagorean theorem:
AB being the hypotenuse can be written as
Substituting values of side BC and AC
Taking square roots both sides:
∴
Answer:
b
Step-by-step explanation:
(x√7-3√8)(x√7-3√8)= (x√7)²-2*x√7*3√8+(3√8)²=7x²- 6x*2*√14+72=
=7x²- 12x*√14+72
The equation that is equivalent to the given logarithmic equation is 3² = x + 5. The correct option is the third option 3² = x + 5
