If sin(y degrees) = cos(x degrees), which of the following statements is true?

grin007 [14]

Answer:

Angle y and Angle x are complementary angles

Step-by-step explanation:

we know that

sin(y°)=cos(x°)

then

Angle y and Angle x are complementary angles

∠y+∠x=90°

∠x=90°-∠y

sin(y°)=cos(90°-y°)

therefore

The sine of an angle is equal to the cosine of its complementary angle

4. Liam can work at most 20 hours a week but he needs to earn at least $125. His dog-walking job pays

Oxana [17]

Two possible solutions are: (4.5, 8.5) and (8, 6.3)

<h3>How to graph the inequality?</h3>

Let x represents hours dog walking and y represents hours washing cars.

So, we have:

Earnings = Rate of dog walk * x + Rate of car wash * y

This gives

Earnings = 7x + 11y

He wants to earn at least $125.

This means that:

7x + 11y ≥ 125

See attachment for the graph of the inequality

From the attached graph, two possible solutions are: (4.5, 8.5) and (8, 6.3)
