Neporo4naja [7]3 years ago
7 0

Answer:

y = 10

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = \frac{1}{2} , then

sin30° = \frac{opposite}{hypotenuse} = \frac{y}{20} = \frac{1}{2} ( cross- multiply )

2y = 20 ( divide both sides by 2 )

y = 10

A square has a side of 8cm. The area of the square increases by 50%. Work out the percentage increase in the length of the side.
sertanlavr [38]
Because the side has to be increased by 50% 
you find half of 8, which is 4 and you add 8+4 because you add the increased amount
8+4=12
you then just find the area.... so 12x12= 144
