The lengths of the three sides of a triangle (not necessarily a right triangle) are 3.16 meters, 8.25 meters and 10.4 meters. wh
Dafna1 [17]
For non-right triangles you must use the "Law of Cosines"  and then, the "Law of Sines" to solve this<span>.

a= </span> 8.25m<span>
b=</span> 10.4m<span>
c= </span>3.16m
∠<span>A= UNKNOWN
</span>∠<span>B= UNKNOWN
</span>∠<span>C=UNKNOWN

Law of Cosines:
c</span>²= a²+b²-2abCos(C)
(3.16)²= (8.25)²+(10.4)²- 2(8.25)(10.4)(cos(C))
9.9856 = 68.0625 + (108.16) - (171.6)(cos(C)
9.9856 = 176.2225- 171.6 cos C
-166.2369=  - (171.6(cosC))
cosC= 0.968746503
<span>Take the inverse cosine of that to get the measure of angle C
</span>∠C= 15.95813246°
<span>
Now Use law of sines to find </span>∠B:
\frac{10.4}{Sin(B)} = \frac{3.16}{sin(15.96)}
\frac{10.4}{Sin(B)} =12.73922
10.4 =12.73922115(sinB)
sinB= 0.816276439
(take the inverse sine to get the measure of ∠B)
∠B= 60.8040992°
<span>

Answer:
The angle measures approximately 60.80</span>°.<span>

the area of a rectangle with width x and length 7x is 7x^2 what does the coefficient 7 mean in terms of the problem
Nezavi [6.7K]
Area of figure is the total number of 1 square unit in the figure. For a rectangle, it is calculated from the product of its length and its width. For this case, we are given:

Width = x 
Length = 7x
Area = x(7x) = 7x^2

The coefficient 7 would mean that the length is 7 times longer than the width, x.
