The first poster is not an accurate representation of the painting, but the second poster is an accurate representation because the ratio between the first and original lengths did not equal the ratio between the first and original widths but the second poster's ratios were equal.
IN the given figure.
angle A + angle B + angle C = 180°
( angle sum property of Δ)
58°+47°+ x = 180°
105°+ x =180°
x = 180° - 105°
<h3>x = 75°</h3>
thus correct option is (d)
hope this will help u!!
Answer:
2 - 2 cos²x = sin x
2 = sin x + 2 cos² x
0 = -2 + sin x + 2(1 - sin² x)
0 = -2 sin² x + sin x + 2 - 2
0 = 2 sin² x - sin x 0 = sin x (2 sin x - 1)
sin x = 0 v sin x = 0.5
x10° + k.360° x1 = 0°, 360°
x2 = (180° - 0°) + k.360°
x2 = 180°
x3 = 30° + k.360°
x3 = 30°
x4 = (180° -30°) + k.360° x4 = 150°
HP: {x | 0°, 30°, 150°, 180°, 360°)
The original price when Mr. Razali bought the laptop was $2500
Working backwards to solve the problem
If Mr. Azmi lost 20% when he sold the laptop for 2400, that means that he sold it for 80% of what he paid. If 2400 is 80% of what he paid, then to find out what he paid for it you would use this equation to determine what 100% would be:

cross multiply to get:
240000 = 80x
3000 = x
Mr. Azmi bought the laptop for $3000
Mr. Razali sold the laptop for a profit of 20%, which means he sold it for 120% of what he paid for it. To determine how much he bought it for we would use this equation:

cross multiply to get:
120x = 300000
x = 2500
Mr. Razali initially bought the laptop for $2500
