Solve for c of the right triangle

Mathematics

In order to solve this triangle we must use cosine law:
c^{2} = a^{2} + b^{2} - 2ab*cosC

Now let's plug in the values we are given:
c^{2} = 5^{2} + 8^{2} - 2(5)(8) * cos 67
c^{2} = 25 + 64 - 80*cos67
c =  \sqrt{80-cos67}

From the Law of Cosines, we know
<span>b=8 a=5 angle C=67
side c² = a² + b² -2ab • cos(C)
</span><span>side c² = 5^2 +8^2 -2*5*8 * cos (67)
</span><span>side c² = 25 + 64 -(80*.39073)
</span>side c² = 89 - <span> <span> <span> 31.2584 </span> </span> </span>
<span><span><span>side c² = 57.7416 </span> </span> </span>
side c = <span> <span> <span> 7.5987893773 </span> </span> </span>

Find the length of MN.<br> A) 7 <br> B) 25 <br> C) 32 <br> D) 39
MrRissso [65]

Step-by-step explanation:

Answer C)

Explanation:

MN + NP = MP

MP = 39

Therefore, 4(x + 5) + 2x + 1= MP

So, 4(x + 5) + 2x + 1= 39

(4x + 20) + 2x +1 = 39

So, (4x + 2x) + (20 + 1) = 39

6x + 21 = 39

Addition changes to Subtraction

So, 6x = 39 - 21

6x = 18

Multiplication changes to Division

x= 18/6

x=3

Therefore MN = 4(x + 5)

So, 4(3 + 5) = 4(8)

4(8) = 32

Therefore, MN = 32

Hope this helps!
