Answer:
Step-by-step explanation:
The tangent to the angle makes an angle of 90° with the radius.
The interior angle of the equilateral triangle is 60, so that leaves 90-60 = 30° for the remaining angle with the tangent.
By the exterior angle theorem, 30°+x° = 60° (interior angle of the equilateral triangle), therefore
x = 60-30 = 30°.
Solve the equation 1/30 + 1/45 = 1/x
where x is the required time
multiply thru by 90x:-
3x + 2x = 90
x = 90 / 5 = 18
answer 18 minutes
Answer:
The answer is AS A Congruence Postulate.
Step-by-step explanation:
Answer:
x = -2
Step-by-step explanation:
If it’s parallel to the y-axis, it must be an x value that is straight up and down. The x coordinate here is -2 so the line must be vertical from -2 on the x-axis.
