Answer:
Step-by-step explanation:
Since we are given a right triangle, we can use the trigonometric ratios.
- sin(θ)=opposite/hypotenuse
- cos(θ)= adjacent/hypotenuse
- tan(θ)=opposite/adjacent
We have the angle 24 and the sides 9 and x. 9 is the hypotenuse because it's opposite the right angle. x is the opposite, because it as across from the 24 degree angle. So, we have:
Therefore, we must use sine.
We are trying to solve for the value of x, so we must isolate the variable. x is being divided by 9. The inverse of division is multiplication. Multiply both sides by 9.
Round to the nearest tenth. The 6 in the hundredth place tells us to round the 6 to a 7.
x is approximately <u>3.7</u>
Are you allowed to use a calculator? if you are allowed, for number 13 you should put “If you put 678 into a calculator and divide it by 2, you get 339. If you divide it by 3, you get 226. And if you divide it by 6, you get 113.”They are all numbers without decimals.
I’m not sure about 14 though. Sorry :( But i hope i helped.
Tan(theta)=opposite/adjacent
Tan(31)=x/10
(Tan(31))10=x
X=6.0086
