The objective in this question is to get rid of the 8 on the left. When you do that you will have all the numbers on the right, and all the variables on the left. The equation will be solved. If the solution is not what you want, then be a little bit more careful about how you post a question.

Add 8 to both sides.

n +8 - 8 = - 10 - 8

n = - 18 Think money when you do the question. If you owe 10 dollars and you spend 8 more, you go more and more in debt. That's the same way with this question. You go more and more negative.

ANSWER FAST ITS URGENT

Vlad1618 [11]

Answer:

9) 6.3 units

11) n=6√2 and m=12,

10) m=6√3, n=6

12) 330.6 ft

Step-by-step explanation:

1) The Pythagoras Theorem says that, the square of the hypotenuse is the sum of the squares of the two shorter legs.

Let the missing side, which is the hypotenuse be x.

Then

${x}^{2} = {2}^{2} + {6}^{2}$

${x}^{2} = 4 + 36$

${x}^{2} = 40$

$x = \sqrt{40}$

$x = 6.3$

The missing side is 6.3 units to the nearest tenth.

2) This is an isosceles right triangle.

This implies that, the two legs are equal.

$n = 6 \sqrt{2}$

The hypotenuse can be found using Pythagoras Theorem.

${m}^{2} = {(6 \sqrt{2} )}^{2} + {(6 \sqrt{2} )}^{2}$

${m}^{2} = 36(4)$

$m = \sqrt{36 \times 4} = 6 \times 2 = 12$

3) The side lengths of 30°-60°-90° are in the ratio, 2x,x√3,x

From the diagram, the hypotenuse is 12, therefore the other two legs are

$n = \frac{1}{2} (12) = 6$

and

$m = 6 \sqrt{3}$

4) The height of the monument is 115 feet, the hypotenuse is 350.

By Pythagoras Theorem,

${x}^{2} + {115}^{2} = {350}^{2}$

${x}^{2} = {350}^{2} - {115}^{2}$

${x}^{2} = 109275$

$x = \sqrt{109275} = 330.6 ft$

Use the figure to find m.

elena-14-01-66 [18.8K]

Answer:

m = 10

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adj side / hypotenuse

cos 30 = 5 sqrt(3) / m

m cos 30 = 5 sqrt(3)

m = 5 sqrt(3) / cos 30

m = 5 sqrt(3) / sqrt(3)/2

m = 5 / (1/2)

m = 10
