First, you have to know what is the law of Sine?
(Refer to this website for more information: https://www.mathsisfun.com/algebra/trig-sine-law.html )
<span>a/sin A</span><span> = </span><span>b/sin B</span><span> = </span><span>c/sin C
in this case: 13/sin59=14/sinB, => sinB=(sin59)*14)/13 use your calculator:
B is about 67 degree.
the three angles make a total of 180 degree, so C=180-59-67=54
again, use law of sin, to find out c
13/sin59=c/sin54 =>c is about 12
I don't see how to form the other triangle.</span>
Answer:
The answer to your question is: 32 x + 2y - 107
Step-by-step explanation:
Simplify 5+2{y-4[3x+7(2-x)]}
5 + 2 { y - 4[ 3x + 14 - 7x ]}
5 + 2 { y - 12x -56 +28x }
5 + 2y - 24 x - 112 + 56x like terms
32 x + 2y - 107
54 square inches
Basically you just multiply
