8 0

Answer:

61 degrees

Step-by-step explanation:

First, find x. CBD=BDA

x+18=4x-15

x=11

Four interior angles of a rectangle are all 90 degrees. So to find ABD, subtract CBD from 90 degrees. So 90-29=61 degrees.

The price of a computer was decreased by 7% to £500. What was the price before the decrease? Give your answer to the nearest pen

makkiz [27]

Answer:

£ 537.63

Step-by-step explanation:

original price = 100%

selling price = 100% - 7% = 93% = £500

just do the proportion or ratio

$\frac{100\%}{93\%} = \frac{original \: price}{500}$

OP = 500 x 100% / 93%

OP = £ 537.634

rounded to the nearest penny and become £ 537.63
