Answer:

A, E

Step-by-step explanation:

Remember SOH-CAH-TOA:

Sine = Opposite / Hypotenuse

Cosine = Adjacent / Hypotenuse

Tangent = Opposite / Adjacent

Therefore, we can say:

sin 20° = LN / 8

cos 70° = LN / 8

tan 70° = MN / LN

Only the first and last options are correct.

Find the radius of the circle whose equation is 3x² + 3y² = 75.
Flauer [41]

Answer:

<h2>A) 5</h2>

Step-by-step explanation:

The equation of a circle:

(x-h)^2+(y-k)^2=r^2

(h, k) - center

r - radius

We have the equation:

3x^2+3y^2=75             <em>divide both sides by 3</em>

x^2+y^2=25\to r^2=25\to r=\sqrt{25}\to r=5
