Answer:

Q1.

AC is the greatest side, therefore is hypotenuse. AB and BC are legs.

B is 90 deg as the two legs cross at this point.

<u>Ratios:</u>

sin = opposite / hypotenuse
cos = adjacent / hypotenuse
tan = opposite / adjacent

BC is opposite to A and adjacent to C

AB is adjacent to A and opposite to C

sin A = cos C = 8/10 = 4/5
cos A = sin C = 6/10 = 3/5
tan A = cot C = 8/6 = 4/3
tan C = cot A = 6/8 = 3/4

Solve for q. √3q + 2 = √5

34kurt

Answer:

$q = 0.0186$

Step-by-step explanation:

To solve for q, we initially place everything with the term q to one side of the equality, and everything without the term q to the other side of the equality.

$\sqrt{3q} + 2 = \sqrt{5}$

$\sqrt{3q} = \sqrt{5} - 2$

We find the square of both sides of the equation. So

$(\sqrt{3q})^{2} = (\sqrt{5} - 2)^{2}$

$3q = 0.0557$

$q = \frac{0.0557}{3}$

$q = 0.0186$
