Answer:
3.6 cm²
Step-by-step explanation:
18 mm = 1.8 cm
A = 2cm×1.8cm = 3.6 cm²
First solve the triangle:
75° + 75° + x = 180°
150° + x = 180°
x = 180° - 150°
Therefore x = 30°
Then, use the geometrical property of vertically opposite angles.
Therefore. x° = 30°
X% of 150 = 108
x/100 * 150 = 108
1.5x = 108
x =108 / 1.5
x = 72
Therefore 72% of 150 is 108
Hope this helps.
Answer:
convert 3 1/3 to an improper fraction
3*3 = 9
9+1 = 10
10/3
multiply the numerator by 4
(10/3) * 4 = 40/3
40/3 = 13 1/3
