What is the length of the side labeled x cm?
UkoKoshka [18]
When we know 2 angles and one side, we use the Law of Sines.
First we need to find that third angle.
Angle A =
180 -41 -62 = 77 degrees

The Law of Sines states that

side a / Sine (A) = side x / Sine (X)
14 / Sine (77) = side x / Sine (41)

14 * Sine (41) / Sine (77) = side x

side x = 14 * 0.65606 / 0.97437
<span>side x = 9.18484 / 0.97437
</span>
<span> <span> <span> side x = 9.4264396482 </span> </span> </span>

(x+3)(x+3)=0

either

x+3=0

x=-3

or

x+3=0

x=-3

Step-by-step explanation:

next method

x²+6x+9=0

x²+2×x×3+3²=0

it is in formula of (x+y)²

(x+3)²=0

x+3=√0

x+3=0

x=-3
