12.=0.06
13. =-5.12
14. =0.5
Step-by-step explanation:
12. .1 + .2 -.3 x.4/.5
.1+.2 -.12/.5
.1+.2-.24
.3-.24=.06
13. 3.2^2
10.24-15.36=-5.12
14. 4.2 x5/6 /10 +3/20
3.5 / 10 + 3/20
0.35+3/20
7/20+3/20=10/20
0.5

Hypotenus = 17
Tan B:
Using the trigonometric relation :
Tan B = opposite / Adjacent
Tan B = 15 / 8
