The measure of an angle is 90 degrees what is the measure of it’s supplementary angle

1 answer:

7 0

Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.So the equation to solve this would be simply 90 multiply 2 which gives you the answer of 180 degree in this situation.

Let ∠X and ∠Y be complementary. If sin(X) = 3/5

statuscvo [17]

Since they are complementary
x + y = 90

Sin(o) = Cos (90-0)

Therefore, Cos x = Sin y = 4/5 [ Because x and y are complementary]

A farm has sheep,pigs and cows at a ratio of 8:3:2. There are 10 cows, how many pigs and sheep are there

dedylja [7]

15 pigs and 40 sheep

10 cows is equivalent to 2 parts of the ratio, hence

$\frac{10}{2}$ = 5 ← 1 part of the ratio, hence

8 parts = 8 × 5 = 40 ← number of sheep

3 parts = 3 × 5 = 15 ← number of pigs

the proper angle for a ladder is about 75 degrees. from the ground. suppose you have a 9 foot ladder. how far from the house sho

icang [17]

ANSWER:

2.33 foot

STEP-BY-STEP EXPLANATION:

We can calculate the distance from the staircase to the wall, by means of the trigonometric cosine ratio, which is the following:

$\begin{gathered} \cos \theta=\frac{\text{ adjacent}}{\text{ hypotenuse}} \\ \theta=75\text{\degree} \\ \text{ hypotenuse = 9 foot} \\ \text{adjacent = x} \end{gathered}$

Replacing and solving for x:

$\begin{gathered} \cos 75=\frac{x}{9} \\ x=9\cdot\cos 75 \\ x=2.33 \end{gathered}$

The distance would be 2.33 foot
