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!
Step-by-step explanation:
Write thirteen thousandths in standardform, and expanded form using fractions and then using decimals. Turn and share with your partner. Writethe number on a place value chart thenwrite it in expanded form using fractions or decimals to express the decimal place value units
190 / 40 = $4.75 an hour
4.75 • 60 = 285
At the same rate, he should be paid<span> $285</span> for 60 hours of work
The number of intersections is the number of solutions
we can see they are paralell so they will never intersect
0
C is the answer
