Find the missing angel ​

Mathematics
1 answer:
kolezko [41]4 years ago
8 0

Answer:

x=25°

Step-by-step explanation:

The given angle is a 90° angle. We know this because of the little square in the corner. This means that both angles must add up to 90°:

x+y=90

Insert the known values:

x+65=90

Solve for x. Subtract 65 from both sides:

x+65-65=90-65\\\\x=25

The missing angle, x°, is 25°.

kest kuy is offering a sale on its laptop computers with a 20 percent discount off its original price. there is 8% sales tax add
iVinArrow [24]

Answer:

y = 0.88x

Step-by-step explanation:

Given

Discount = 20\%

Sales\ Tax = 8\%

Required

Determine the final price

First, we need to determine the sales price after the discount.

Discount = 20\% * x

Discount = 0.20 * x

Discount = 0.20x

Sales\ Price = x - Discount

Sales\ Price = x - 0.20x

Sales\ Price = 0.80x

Next, is to determine the sales tax.

Sales\ Tax = 8\% * x

Sales\ Tax = 0.08 * x

Sales\ Tax = 0.08x

Final Price, y is then calculated as thus:

y = Sales\ Price + Sales\ Tax

y = 0.80x + 0.08x

y = 0.88x
