Answer:
<h2>7.4inches</h2>
Step-by-step explanation:
Check the attachment for the diagram. Sine rule will be used to get the unknown side of the triangle.
According to the rule;
![\frac{u}{sinU} = \frac{v}{sinV} = \frac{w}{sinW}\\\frac{u}{sinU} = \frac{w}{sinW}](https://tex.z-dn.net/?f=%5Cfrac%7Bu%7D%7BsinU%7D%20%3D%20%20%5Cfrac%7Bv%7D%7BsinV%7D%20%3D%20%5Cfrac%7Bw%7D%7BsinW%7D%5C%5C%5Cfrac%7Bu%7D%7BsinU%7D%20%3D%20%5Cfrac%7Bw%7D%7BsinW%7D)
Given w = 3 in, ∠W=23° and ∠U=73°, on substituting into the equation above to get u we have;
![\frac{u}{sin73^{0} } = \frac{3}{sin23^{0} }\\usin23^{0} = 3sin73^{0}\\u = \frac{3sin73^{0} }{sin23^{0} }\\u = \frac{2.87}{0.39} \\u = 7.358\\u = 7.4in](https://tex.z-dn.net/?f=%5Cfrac%7Bu%7D%7Bsin73%5E%7B0%7D%20%7D%20%3D%20%5Cfrac%7B3%7D%7Bsin23%5E%7B0%7D%20%7D%5C%5Cusin23%5E%7B0%7D%20%3D%203sin73%5E%7B0%7D%5C%5Cu%20%3D%20%5Cfrac%7B3sin73%5E%7B0%7D%20%7D%7Bsin23%5E%7B0%7D%20%7D%5C%5Cu%20%3D%20%5Cfrac%7B2.87%7D%7B0.39%7D%20%5C%5Cu%20%3D%207.358%5C%5Cu%20%3D%207.4in)
The length of u is 7.4inches to nearest 10th of an inch
Answer:
( B.) 6, 1, -2 , -4
Step-by-step explanation:
A coefficient is a number multiplied by a variable. So, in this case let's take a look at the problem.
-2+6y+m-2y+8-4m
Now we have to find the numbers that have a variable next to it
which are 6,m,-2, and -4
(If you are wondering that why m is a coefficient its because it is also known as 1m)
Final answer = 6, 1, -2 , -4
Hope this helps!
