The sum of adjacent angles on a straight line would be 180°.
Since x is on a straight line,what we need to do is to deduct the remaining two angles,here's what the equation would be like:
180°-90°-30°
=60°
Thus,x=60°
hope it helps!
No because they are straight lines, they cannot curve to intersect more than once, think of a capital X.
Answer:
9 or 3.8x10^-6
Step-by-step explanation:
By flipping a coin you'd look at how many times a head could appear (1/2) and multiply that by the 18 times.
Another explanation:
I'm not sure on this but would you raise 1/2 to the 18th power?
Answer:
x = 1
y = -3
Step-by-step explanation:
if y = x - 4
then reorganise the first equation
4 (x - 4) = 9x -21
4x - 16 = 9x - 21
5 = 5x
x = 1
