The x-axis is the vertical axis.
True
False

False

Step-by-step explanation:

the x-axis is the horizontal axis

None

Step-by-step explanation:

We are given the angles of a triangle as 90°, 60° and 60°

In order for these angles to construct a triangle, the sum of the three angles must be 180°.

So, we get that,

90° + 60° + 60° = 90°  + 120° = 210°

Since, the sum of the angles is not 180° .

Therefore, no triangle can be drawn using the angles 90°, 60° and 60°.

Hence, last option is correct.
