<span>2x+5=10

Subtract 5 from both sides.
2x + 5 - 5 = 10 - 5
2x = 5

Divide both sides by 2.
2/2x = 5/2
x = 5/2

5/2 can be simplified to 2 1/2 or 2.5.</span>

Use the triangle below to find the following trig ratios. Express your answer as a fraction.

Luda [366]

Answer:

Step-by-step explanation:

First we need the length of the hypotenuse.

20^2 + 21^2 = c^2

400 + 441 = c^2

841 = c^2

29 = c

If you are using angle B as your theta (angle from which the relations are formed:

a) sin = O/H = 20/29

b) cos = A/H = 21/29

c) tan = O/A = 20/21
