Answer:
39°
Step-by-step explanation:
If it gives you 2 angles and asks for x, you know it has 3 angles. So the shape is a triangle. All 3 angles in a triangle add up to 180°.
So add 78 and 63 which equals 141
And to find x, subtract 141 from 180 because 180 is the total.
So the answer is 39
The answer is 0.79. I know it's the answer I am a genius in math.
Possible dimensions:
40 x 1
20 x 2
4 x 10
5 x 8
since 10 is 6 more than 4, the length is 10 and the width is 4
General equation of the line is
y = mx + c
c = -3
m = 3
so the equation is
y = 3x - 3
