Since those lines are parallel, those two angles are equal. Therefore:
3x+15=105
3x=90
x=30

Answer:
1/4=0.25=25%
Step-by-step explanation:
A coin has two sides, heads and tails, and if you take 100% divided by two you get 50, you want to know what is the probability it will land on tails TWICE so divide 50 by two and you get 25.
1/2=50
1/4=25
0.25 x 100= 25%

Answer:
25.12 cm²
Step-by-step explanation:
The area of a circle is given by the formula ...
A = πr²
where r is the radius. Here, the diameter is given as 8 cm, so the radius will be half that, or 4 cm. The area is then ...
A = 3.14(4 cm)² = 50.24 cm²
The green shaded part is 1/2 a circle, so is half this area:
shaded area = 25.12 cm²
