Answer:
The answer is 108 cm²
Step-by-step explanation:
First, you have to find the height of the parallrelogram using trogonometric formula, sinθ = oppo./hypo. :
oppo. = height
hypo. = 9 cm
θ = 59°
sin 59° = height/9
height = 9 sin 59°
= 7.715 cm (4s.f)
Given that the formula of area of parallelogram is, A = base×height. Then, you can substitute the value into the formula :
base = 14 cm
height = 7.715 cm
A = 14 × 7.715
= 108 cm² (3s.f)
Complementary angles add up to 90°. The complement of a 27° angle is 90°-27°= 63°.
Supplementary angles add up to 180°. The supplement of a 27° angle is 180°-27°=153°

The correct equation of 146 ÷ 7 = 20857 is 146.0 ÷ 7.0 = 20.857
<h3>How to divide the decimals?</h3>
The equation is given as:
146 ÷ 7 = 20857
The above equation is wrong.
The equation can be rewritten as:
146.0 ÷ 7.0 = 20857
The significant digits in 146.0 and 7.0 are 3 and 1, respectively.
3 - 1 = 2
This means that
So, the decimal place in the result must be after the second digit.
So, we have:
146.0 ÷ 7.0 = 20.857
Using the above highlights, we have:
146 ÷ 0.7 = 208.57
1.46 ÷ 7 = 0.20857
14.6 ÷ 0.7 = 20.857
1460 ÷ 70 = 20.857
The reasoning behind the above equations is that the decimal position in the results is dependent on the decimal positions in the dividend and divisor
