In ΔUVW, u = 44 inches, ∠W=56° and ∠U=117°. Find the length of v, to the nearest inch.
Arisa [49]

Answer:

The length of v is 6 inches

Step-by-step explanation:

Here, we want to calculate the length of v to the nearest inch

The best way to go about this is to use the sine rule

But before we proceed, we need the measure of angle V

Mathematically, since we have a triangle

W + U + V = 180

This is the sum of angles in a triangle

56 + 117 + V = 180

V = 180-56-117

V = 7 degrees

so we proceed to use sine rule to get the length of v

Mathematically;

v/Sin V = u/Sin U

Thus;

v/sin 7 = 44/sin 117

v = 44sin 7/sin 117

v = 6.018

This is approximately 6 inches

Find the values of the variables ( I have five more of these if you will help me pls)
lord [1]
<span>The angles of the figure are complementary, that is, the sum between them is equal to 90º.

Solving:
54º + 4xº = 90º
4xº = 90 - 54º
4xº = 36º
</span>x =  \frac{36^0}{4^0}
\boxed{\boxed{x = 9^0}}\end{array}}\qquad\quad\checkmark
<span>
We have:
54º + 4.xº = 90º
54º + 4.(9º) = 90º
54º + 36º = 90º
90º = 90º (TRUE)

Answer:
</span><span>The value of the variable is 9º</span>

He speeds (in MPH) of automobiles traveling in a city are given below:
professor190 [17]

Answer:

Mean speed = 41.3 mph

Step-by-step explanation:

Given that,

The speeds of an automobiles are given below:

20, 35, 42, 52, 65, 49, 24, 37, 23, 41, 50, 58

We need to find the mean speed of the cars.

Mean = sum of observations/ no. of observation

M=\dfrac{20+35+42+52+65+49+24+37+23+41+50+58}{12}\\\\M=41.3

So, the mean speed of the cars is equal to 41.3 mph.
