Suppose that A and B are angles in standard position. Use the given information to find (a) sin(A + B), (b) sin (A-B), (c) tan (A + B), (d) tan (A-B), (e) the quadrant of A+B, and (f) the quadrant of A-B.
Cos A = and sinB = - 3 7

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant

then i saw it was a trapezoid or a quadrilateral

if im not mistaking its
