Answer:
Step-by-step explanation:
These "special" right triangles have side length ratios that it is useful to remember.
<u>45°-45°-90° triangle</u>
Sides have the ratios 1 : 1 : √2. That is, x is √2 times as long as the side length shown as 18.
x = 18√2
<u>30°-60°-90° triangle</u>
Shortest to longest, sides have the ratios ...
1 : √3 : 2
That is, y is √3 times the length of the side marked 18, and z is 2 times the length of the side marked 18.
y = 18√3
z = 2·18 = 36
Answer:
y = -2/3x + 2
Step-by-step explanation:
2x + 3y = 6 to y = mx + b form.
1. Subtract 2x from both sides.
3y = -2x + 6
2. Divide each side by 3.
y = -2/3x + 2

Answer:
34.58 in
Step-by-step explanation:
Relative to the angle marked in this right triangle, the side given is the "adjacent" side, and the side length wanted is that of the hypotenuse. The relevant trig relation is ...
Cos = Adjacent/Hypotenuse
Solving for the hypotenuse, we get ...
NP = (29 in)/cos(33°) ≈ 34.58 in
120 feet
To find area you need to follow the formula l • w, which is 12 x 10, that equals 120
4 x - 5 y = 9
- 5 y = - 4 x + 9 / · ( - 1 )
5 y = 4 x - 9 / : 5
