Question

I need to find the measure of each angle indicated and round to the nearest tenth.

Answer 1

Okay so because of the due to the rule that the hypotenuse is always the longest side on right angles so with the Pythagorean theorem we can infer that

a^2+b^2=c^2

19) 9.3^2+b^2=13.2^2
86.49+b^2=174.24
b^2=87.75
B=9.367

20) 2^2+b^2=7^2
b^2=45
b=6.708

21) 5^2+4^2=c^2
c^2=41
b=6.403

22) 15^2+15^2=c^2
c^2=450
c=21.213

23) 10^2+b^2=12^2
b^2=44
b=6.633

24) 6^2+b^2=9^2
b^2=45
b=6.708
