Rasek [7]3 years ago

4 0

Answer:

Your score is 100.

Step-by-step explanation:

If you have -300 and add +300 you will end up with 0 because when a positive and a negative that are equal cancel each other out. So if you add +300 to -300 you get 0 but its 400 so 300 + 100 is 400 so you have +100 left. : )

<h3>Answer: 8 = g/3</h3>

Explanation:

When translating word problems into equations, the word "is" often means "equal sign"

The term quotient is the result of a division problem. So "quotient of g and 3" means "g divided by 3" or g/3.

Solve the right triangle given that mZA= 30°, mZC = 90°, anda = 15. Round your result to one decimal place.

Genrish500 [490]

Answer:

$\angle B = 60^o$

$b =17.3$

$c = 20$

Step-by-step explanation:

Given

$a= 15$

$\angle A = 30^o$

$\angle C = 90^o$

<em>See attachment for illustration</em>

Required

Solve the triangle

First, we calculate the measure of B

$\angle A + \angle B + \angle C = 180^o$ --- angles in a triangle

$30^o + \angle B + 90^o = 180^o$

Collect like terms

$\angle B = 180^o-90^o-30^o$

$\angle B = 60^o$

Solve for (c) using sine function

$\sin(30) = \frac{a}{c}$

Make c the subject

$c = \frac{a}{\sin(30)}$

Substitute known values

$c = \frac{10}{0.5}$

$c = 20$

Solve for (b) using Pythagoras

$c^2 = a^2 + b^2$

This gives:

$20^2 = 10^2 + b^2$

$400 = 100 + b^2$

Collect like terms

$b^2 =400 - 100$

$b^2 =300$

Take square roots

$b =17.3$
