PLEASEEE I need the answer asap

Angle B = 47.3°

Step-by-step explanation:

We are to find Angle B

b = 6.8cm

C = 70°

c = 8.7cm

We solve using Sine rule

b/sin B = c/ sin C

6.8/sin B = 8.7/sin 70

Cross Multiply

sin B × 8.7 = 6.8 × sin 70

sin B = 6.8 × sin 70/8.7

B = arc sin ( 6.8 × sin 70/8.7)

B = 47.26265°

Approximately to 3 significant figures

= B = 47.3°

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
