sin x = cos 54 = sin (90-54) = sin 46
Hence x = 46 deg
Same technique. Sin 21 = cos (5x+9) = sin (90-5x-9)
81-5x = 21
Or 5x = 60
Or x = 12 deg

Answer:
95.1CM²
Step-by-step explanation:
THERE ARE 3 SHAPES
-AREA OF RECTANGLE=LXB
=21 X 3 = 63 CM²
-AREA OF SQUARE = SXS
=5 X 5= 25CM²
-AREA OF CIRCLE = Pi x r²
RADIUS = HALF OF DIAMETER = 1.5
=3.14 X 1.5 ²
=3.14 X 2.25
=7.065
TOTAL AREA= 63 + 25 + 7.065=
ROUNDED = OPTION B
=95.1 CM²
