Total for all triangles=180
Step-by-step explanation:
In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:
3y+2y+y=180
6y=180
y=30
It's fairly easy to solve from there. Just more multiplying and subtracting.

Step-by-step explanation:
A triangle<span> can't have more than one </span>right angle<span> to begin with. If it had 2 </span>rightangles<span>, then it is no longer a </span>triangle<span>. The </span>angles<span> of the </span>triangle<span> ha…ve to add up to 180 degrees and a </span>right angle<span> is 90 degrees. So if you had two </span>right angles<span> you would already be at 180 degrees. hope </span>that helped

The axis of symmetry of the quadratic equation y = 2x^2 + 3 is x = 0
<h3>How to determine the axis of symmetry?</h3>
The equation is given as:
y = 2x^2 + 3
Differentiate the above equation with respect to x
y' = 4x + 0
This gives
y' = 4x
Set the equation to 0
4x = 0
Divide both sides by 4
x = 0
Hence, the axis of symmetry is x = 0
