The above expression supports
Answer:
B= 21° C= 29°
Step-by-step explanation:
Use sin rule.
1st one.
sin44°/33 = sinB/17
sinB= 17sin44/33
B= sin^-1 ( ans)
B= 20,97 =21°
2nd one.
sin92°/35 = sinC/17
sinC = 17sin92°/35
C= sin^-1 (ans)
C= 29,04° = 29°
Answer:
the answer to the question is 15$
Answer:
0.115
Step-by-step explanation:
First, multiply 0.25 x 46 to get 11.5
Then, multiply by 11.5 x 100 and get your answer.
You can find the percent of any number my doing this:
Multiplying the percent x the number then dividing by 100
hope this helps :)
