Find side x , give your answer 1 decimal place

Vladimir [108]

Given:

Let A denote the angle of the given triangle which measures ∠A = 81°

Let B denote the angle which measures ∠B = 40°

The length of the side a = x.

The length of the side b = 7 cm.

We need to determine the value of x.

Value of x:

The value of x can be determined using the law of sine formula.

Applying the law of sine, we have;

$\frac{sin \ A}{a}=\frac{sin \ B}{b}$

Substituting the values, we have;

$\frac{sin \ 81^{\circ}}{x}=\frac{sin \ 40^{\circ}}{7}$

Simplifying, we get;

$\frac{0.988}{x}=\frac{0.643}{7}$

Cross multiplying, we have;

$0.988 \times 7=0.643 x$

$6.916=0.643x$

$10.8=x$

Thus, the length of the side x is 10.8 cm.

Once a week you babysit your neighbor’s toddler after school, usually going to a local playground. You notice that each swing on

Ira Lisetskai [31]

Answer:

3.9 units

Step-by-step explanation:

We are given that,

Time taken by each swing = 2.2 seconds

The pendulum formula is given by, $T = 2\pi \sqrt{\frac{L}{32}}$ , where T is the time taken and L is the length of the swing.

So, we have,

$2.2= 2\pi \sqrt{\frac{L}{32}}$

i.e. $\frac{2.2}{2\pi}=\sqrt{\frac{L}{32}}$

i.e. $(\frac{2.2}{2\pi})^{2}=\frac{L}{32}$

i.e. $L=32\times (\frac{2.2}{2\pi})^{2}$

i.e. $L=32\times \frac{4.84}{4 \pi^2}$

i.e. $L=32\times \frac{1.21}{\pi^2}$

i.e. $L=\frac{38.72}{9.87}$

i.e. L = 3.923 units

So, rounded to tenths, the length of the swing is 3.9 units.

What is c/22 + 668 = 684 I NEED HELP!!!!!!!!!!!!!!

scoundrel [369]

Answer:

352

Step-by-step explanation:

So first you need to subtract 668 from both sides.

c/22 + 668 = 684

-668 -668

---------------------------

c/22 = 16

Then multiply both sides by 22.

c/22 * 22 = 16*22

c = 352

Check-

352/22=16

16+668=684
