Question 6 options:

35.75°


71.5°


54.25°


161.5°

Answers

Answer:

\theta=54.25\°

Step-by-step explanation:

we know that

When the sine of angle X is equal to the cosine of angle Y, then angle X and angle Y are complementary angles

so

X+Y=90\°----> equation A

In this problem

X=\theta

Y=(\theta-18.5)

substitute in the equation A

\theta\°+(\theta-18.5)\°=90\°

2\theta=90+18.5

2\theta=108.5

\theta=54.25\°

Answer: A=(2000)/(m)

Step-by-step explanation:

Given : Members of the band sold soda and popcorn at a college football game to raise money for an upcoming trip. The band raised $2,000.

The amount raised is divided  equally among the m members of the band.

Which is greater 45/100 or 6/10? Explain.

20 pts! ^ ^ Please Answer Explaining it .. :l

Answers

6/10 is greater. If you made the number under the top number equal to 100, like the other one (45/100) you would get 60/100 which is greater than 45/100. You can make fractions larger like I did by multiplying both the top and bottom number by the same number, in this case 10

Answer:

6/10

Step-by-step explanation:

6/10 changed into denomination 100 is 60/100 which is larger than 45/100
