Hey there! I'm happy to help!
To find this other side given an angle and a side, we will use a trigonometric function. The three basic ones are sine, cosine, and tangent. You can remember these and what what they are using the mnemonic "soh cah toa".
SOH: Sine= Opposite/Hypotenuse
CAH: Cosine= Adjacent/Hypotenuse
TOA: Tangent= Opposite/Adjacent
We see that the sides involved are the opposite and hypotenuse.
Therefore, we can write this equation.
sin40= w/28
We multiply both sides by 28 to isolate the w.
28×sin40=w
Now, we find the sine of 40 on our calculator and then we multiply it by 28.
w≈18
Therefore, the answer is 18 cm.
I hope that this helps! Have a wonderful day!
At a zoo it has been found that the total amount of bamboo shoots eaten by 3 pandas in a day is 181.5 pounds. Also it is given that the male panda eats 3 times as that of the baby panda and the female panda eats 2 times as that of the baby panda.
Let us assume that the amount of bamboo shoot eaten by the baby panda in a day = X
The amount of bamboo shoots eaten by the male panda in a day = 3X
Amount of bamboo shoots eaten by the female panda in a day = 2X
Then
X + 3X + 2X = 181.5
6X = 181.5
X = 181.5/6
= 30.25
So the baby panda eats a total of 30.25 pounds of bamboo shoots in a day.
The amount of bamboo shoots eaten by the female panda in a single day = 2 * 30.25
= 60.50
So the female panda eats 60.50 pounds of bamboo shoots in a day.
Current area is 5ft * 10ft = 50ft^2.
Increasing by x, you have:
Since length must be positive,
Answer:
14a+35
Step-by-step explanation:
7×2a=14a
7×5=35
=14a+25
