Trigonometry ( solve the right triangle)

B=47.00°

a=18.70

c=27.30

Step-by-step explanation:

Calculation for B

The sum of the interior angles of a triangle is 180°

180°=43°+90°+B°

180=133+B

180-133=B

B=47°

To the nearest tenth=47.00°

Calculation for a

Using SOHCAHTOA

To the nearest tenth=18.70

Calculation for c

Using Pythagoras theorem

c²=18.65²+20²

c²=347.82+400

c²=747.8

√c²=√747.8

c=27.3459

To the nearest tenth=27.30
