Sin(90-A) = cos A
cos(90-A) = sin A

Therefore,

tan(90-A) = sin(90-A)/cos(90-A) = (cos A)/(sin A) = 1/(tan A)

Why aren’t credit cards included in m1 or m2 definition of money?
mel-nik [20]

Credit cards are not considered to be part in the m1 and m2 definition of money. Because the M1 definition of money revolves around money which are in the hands of the public and written checks, while the M2 definition of money revolves around savings accounts, time deposits of under $100,000, and balances in retail money market mutual funds. Which also includes the M1 in the M2. While, the M3 definition of money refers to the balances in institutional money funds, repurchase accountabilities dispensed by depository establishments, and the Eurodollar. It also includes M1 and M2. Credit cards are not considered to be in M1 and M2 definitions of money, since credit cards becomes part of the money transaction only, during the payment of your credit card bill.

Answer:

Step-by-step explanation:

you have to

first multiply the numbers you have in the column with the ones in the rows

8x* 5x = 40x² top left

8x* (-3) = -24x bottom left

-1 * 5x = -5x top right

-1* (-3) = 3 bottom right

second add and subtract all

40x²-24x-5x+3 = 40x²-29x+3

The trigonometric function gives the ratio of different sides of a right-angle triangle. The measure of ∠C is 28°. And the value of b and c is 7.06 and 3.76, respectively.

<h3>What are Trigonometric functions?</h3>

The trigonometric function gives the ratio of different sides of a right-angle triangle.

\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}

where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite the 90° angle.

The sum of all the angles can be written as,

∠A + ∠B + ∠C = 180°

90° + 62° + ∠C = 180°

∠C = 28°

Sin(∠B) = AC/BC

Sin(∠B) = b/8

b = 8 × Sin(62°)

b = 7.06

Cos(∠B) = AB/BC

Cos(∠B) = c/8

c = 8 × Cos(62°)

c = 3.76

Hence, the measure of ∠C is 28°. And the value of b and c is 7.06 and 3.76, respectively.
