Sagot :

Answer:

10

Step-by-step explanation:

Calculating BC

BC = √2^2 + 11^2

BC = √ 4+121

BC = √ 125 = 11.18

to find measure of angle C use sinerule

sinC/C = sinA/A

sinC/2= Sin90/11.18

SinC = 2×1/11.18

sinC = 2/11.18

sinC = (0.1788)

C = sin^-1(0.1788)

C = 10.305

C = 10 (approximately)
