Answer:
Its A and D
Step-by-step explanation:
I found that out the hard way
For A I think it should be 0.16 you just have to look at the chart
a parallel line has the same gradient, so the gradient would be 3 1/3
a perpendicular line has the negative inverse gradient of the original (eg. if the original gradient is 4/3 then the perpendicular gradient would be -3/4 (all you have to do is change the +/- sign and flip the fraction), so in your case the gradient of the perpendicular line would be -3/10 (since 3 1/3 = 10/3)
Answer:
Option A -The height of the building is 105 ft
Step-by-step explanation:
to get the height of the building, we calculate using SOH CAH TOA
TOA = OPPOSITE / ADJACENT
Tan 59° = h / 63
Height = tan 59° X (63)
Height = 1.6643 X 63
Height = 104.85
Height = 105 ft
In a kite, all of the angles added together equal 360. You already know there are two right angles, and because of this, you would subtract 180 from the 360, leaving you with 180. In order to solve for x, you have to add 18x-2 to 12x+2 and set it equal to 180. Your equation would be 18x - 2 + 12x + 2 = 180. The 2's would cancel out, leaving you with 18x + 12x = 180, 30x = 180, then 6 = x.
