Help, I tried it, but I keep getting the wrong answers
Aneli [31]

Answer:

my answer would be that

x = 17.91cm

(i'm not sure about it either but it's worth a try) !!

Step-by-step explanation:

so first off, using the equation given,

" c² = a² + b² — 2ab cos C "

we substitute the values in as,

a = 16

b = 30

then for C is the angle given, which is 30°

so the equation is now,

c² = (16)² + (30)² — 2(16)(30) cos 30°

now, you solve the two squared numbers and the back equation, also known as " 2ab cos C " with your scientific calculator.

so it now equals to,

c² = 256 + 900 — 960(0.87)

c² = 320.8

at last, when you have " c² = 320.8 " ,

remember to square root the answer so you have a smaller value.

so,

c equals to

\sqrt{320.8}

your final answer for the x value will be 17.91

(i hope this helps!)

2(4)-2

Now you can solve the equation:

2(4)-2
