Sin J = cos K
sin J = cos (90 - J)
K = 90 - J

sin 60 = cos (90 - 60) = cos 30

Therefore, 60°, 30° satisfy the condition sin J = cos K.

John had to pay a combined electric and gas bill $150. The electric portion of the bill was $90. What is the ratio of money spen
tatuchka [14]

Given:

John had to pay a combined electric and gas bill $150.

The electric portion of the bill was $90.

To find:

The ratio of money spent on electric to that on gas.

Solution:

Let x be the amount of gas bill.

The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150.  So,

90+x=150

x=150-90

x=60

The gas portion of the bill was $60.

The ratio of money spent on electric to that on gas is:

\text{Required Ratio}=\dfrac{\text{Electric bill}}{\text{Gas bill}}

\text{Required Ratio}=\dfrac{90}{60}

\text{Required Ratio}=\dfrac{3}{2}

\text{Required Ratio}=3:2

Therefore, the ratio of money spent on electric to that on gas is 3:2.
