HAVE A NICE DAY
WILL GIVE BRAINLST :)

1. 30°

2. 46°

3. 55°

Step-by-step explanation: To understand these questions, you need to know that the three angles added together (no matter the size of the triangle) are equal to 180°. All you have to do here is add together the given angles and subtract that from 180°. And there you go! You get the answer, easy peasy!

Hope this helped! ;)

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.

other answer is correct. i had used the radius of the radius somehow. a website:
