In ΔABC, BC = 4 centimeters, m∠B = m∠C, and m∠A = 20°. What is AC to two decimal places?
ipn [44]
M<A = <span>20°
m<B = m<C = 8</span><span>0°

</span>Law of Sines , in any triangle we have
a/sin A = b/sin B = c/sin c<span>

4/sin20 = AC/sin80 = AB/sin80

now we can solve AC

</span>4/sin20 = AC/sin80
<span>AC = 4 (sin80)/ sin20
AC = 4(0.98) / (0.34)
AC = 3.92 / 0.34
AC = 11.52

answer

</span>C.11.52 centimeters<span>

y=9 should be your answer. since there is no x value or "slope" your line will be straight.

Step-by-step explanation:

I have attached what your graph would look like. I hope this helps!!
