Find the value of x, rounded to the nearest tenth.

Mathematics

V125BC [204]3 years ago

Answer:

x=6.2

Step-by-step explanation:

So to find this we can use the trignometric function sin(Θ):

Perpendicular = x

Hypotonuse = 18

Θ = 20°

sin(Θ) = \frac{Perpendicular}{Hypotonuse}

Substituting our values we get:

Sin(20°) =\frac{x}{18}

Using a calculator we get:

0.34202 = \frac{x}{18}

x=0.34202*18

x=6.15636

So rounding that to the nearest tenth :

x=6.2

What is 15% of 140
Mariulka [41]


15% of 40

Of = Multiplication

15% Multiply by 40

Set up a equation

15/100= x/140

Cross Multiply

15* 140= 100*x

2100= 100x

Divide both sides by 100x

2100/100x= 100x/100x

X= 21

What is the gcf of 27 and 72
Leya [2.2K]

Answer:

The GCF of 27 and 72 is 9

Step-by-step explanation:

prime factorization of 27 is 3*3*3

prime factorization of 72 is 2*2*2 by 3*3

3*3 is in both, and so we need to multiply that to get our GCF. 3*# is 9, so the GCF of 27 and 72 is 9
