In ΔABC, BC = 4 centimeters, m∠B = m∠C, and m∠A = 20°. What is AC to two decimal places?

a. 9.32 centimeters
b. 10.01 centimeters
c. 11.52 centimeters
d. 12.09 centimeters

Respuesta :

11.52 centimeters is the answer your're looking for hope h

4/sin20 = AC/sin80

AC = 4 (sin80)/ sin20

AC = 4(0.98) / (0.34)

AC = 3.92 / 0.34

AC = 11.52

C. 11.52 centimeters

It is correct on plato. I just took the test.

Someone please give me brainliest, I need it. Have a great day and I hope this helps you.
