Answer:
Step-by-step explanation:
It's a 30-60-90 triangle. The sides of a 30-60-90 triangle are in the ratio 1:√3:2
The side opposite the 90° angle is 12√3, so the side opposite the 30° is (12√3)/2 = 6√3.
The side opposite the 60° angle is (6√3)√3 = 18
x = 18
y = 6√3
Answer:
first option
Step-by-step explanation:
the working is reallly long im lazy to type hehe sorry
Answer: A
Step-by-step explanation:
X values to the right of the y axis are positive. X values to the left of the y axis are negative.
Y values above the x axis are positive.
Y values below the x axis are negative.
Pairs of coordinates are always noted as (x,y) with the x value of a point given first and the y value of that same point given second.
Capital letters that have rotational symmetry are: Z, S, H, N and O. The letters Z, S, H and N, when rotated 180 degrees clockwise or counterclockwise, will look the same after rotation completion.
Hope it helps you my dear :)
Answer: 15 pounds per inches
Step-by-step explanation:
P1V1 = P2V2
12 ppi × 5L = P2 × 4L
P2 = 12 ppi × 5L / 4L
P2 = 12 ppi × 5 / 4 ( L in denominator is cancelled by L in numerator)
P2 = 3 ppi × 5 ( 12 is cancelled by 4 in denominator)
P2 = 15 ppi
