Solve the equation sin theta = 0.3 to the nearest tenth. Use the restrictions 90degrees < theta < 180degrees.

1 answer:

5 0

We first do:
∅ = sin⁻¹(0.3)
∅ = 17.5°

To go into the second quadrant, we add 90°.
∅ = 17.5 + 90
= 107.5°
The answer is A.

How to simplify the square root of 3 over the square root of 21

Alika [10]

3 * 7 = 21, so

$\sqrt{21}=\sqrt{3\cdot7}=\sqrt3\sqrt7$

Then

$\dfrac{\sqrt3}{\sqrt{21}}=\dfrac1{\sqrt7}$

and you can rationalize the denominator to write this as

$\dfrac1{\sqrt7}\cdot\dfrac{\sqrt7}{\sqrt7}=\dfrac{\sqrt7}7$

Which is smaller 0.9, 75% or four fifths?

zloy xaker [14]

Best way to tell is to convert them all to either decimals, fractions, or percentages. I usually convert to decimals. So, 75% is 0.75. 0.9 is already a decimal. And 4/5 is 0.8. So 0.75, or 75%, is now clearly the smallest. In order from least to greatest, they go 75%, 4/5, and 0.9.
