So if your doing #14, then this is trying to find what x,y,and z are. The way to find this knowing that a triangle is always 180 degrees. If a triangle is always 180 degrees, then that means that the right triangle is 54 degrees + the other two points, which will add up to 180. The box on the bottom left of the right triangle is showing that this angle is a right angle, meaning it's 90 degrees. So you have 90 degrees plus 54 degrees, which equals to 144 degrees. This isn't 180, so what number is needed to make it 180? 36 degrees is the answer, because if you have 54+90+ y= 180 then you find y, 144+y=180, what's y? 36 degrees is y to make it 180 degrees. The same is for the left triangle. Z is the same angle as the right angle on the right triangle, so z is 90 degrees. So we have the problem 52+90+x= 180, meaning 142+x=180. X is 38 degrees, because that is the number needed to make the triangle 180 degrees. So you have y= 36 degrees, x= 38 degrees, and z= 90 degrees. Hope this helps

Area of a rectangle= lb

Area of a square= a^2

Area of the remaining area= lb - a^2

= (12*4) - (2*2)

= 48-4

Bongeka purchased a new refrigerator and were expected to pay R1 684,00 five months ago and another R1 323,00 in eight months’ t
Dmitriy789 [7]

The discount factor computed shows that the value of each payment will be $1546.

<h3>How to calculate the payment?</h3>

The following can be deduced from the information:

Payment due in 5 months = $1684

Payment due in 8 months = $1323

Annual interest  = 11.40%

Monthly interest rate = 11.40%/12 = 0.95%

Present value of payment due 5 months ago = $1684 + (1 + 0.95%)⁵ = $1765.52

Present value of payment due 8 months ago = $1226.62

Total present value = $1765.52 + $1226.62 = $2992.14

After rescheduling, the payments will be in 2 months and 5 months.

Discount factor for payment due in 2 months = 0.9813

Discount factor for payment due in 5 months = 0.9538

Combined discount factors= 0.9360

Therefore, the value of each payment will be:

= $2992.14/(1 + 0.9360)

= $1546
