![$c=\frac{1}{3}](https://tex.z-dn.net/?f=%24c%3D%5Cfrac%7B1%7D%7B3%7D)
Solution:
Given equation is
.
To solve the equation by step by step.
Step 1: Given
![$\frac{8}{3}=3c+\frac{5}{3}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B8%7D%7B3%7D%3D3c%2B%5Cfrac%7B5%7D%7B3%7D%24)
Step 2: Combine like terms together.
Plus symbol changed to minus when the term goes from right to left (or) left to right of the equal sign.
![$\frac{8}{3}-\frac{5}{3}=3c$](https://tex.z-dn.net/?f=%24%5Cfrac%7B8%7D%7B3%7D-%5Cfrac%7B5%7D%7B3%7D%3D3c%24)
Step 3: Subtract the fractions in the left side.
![$\frac{3}{3}=3c$](https://tex.z-dn.net/?f=%24%5Cfrac%7B3%7D%7B3%7D%3D3c%24)
⇒ ![1=3c$](https://tex.z-dn.net/?f=1%3D3c%24)
Step 4: Divide both side of the equation by 3, we get
![$\frac{1}{3} =\frac{3c}{3}$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20%3D%5Cfrac%7B3c%7D%7B3%7D%24)
![$\frac{1}{3} =c$](https://tex.z-dn.net/?f=%24%5Cfrac%7B1%7D%7B3%7D%20%3Dc%24)
Hence, the answer is
.
Sin A = opp/hyp = 4/5
Cos A = adj/hyp = 3/5
Tan A = opp/adj = 4/3
Cos 27 = 0.8910065... --> 0.89
You can just plug that into your graphing calculator, just make sure the degree mode is on.
A. a=145 b=35 c=145 d=145 e=35 f=145 g=35
b. These are the pairs of vertical angles: a & c, b & 35, d & f, e & g.
