30, assuming it's a right triangle

Step-by-step explanation:

The answer assumes this is a right triangle. Otherwise, it's impossible to answer.

The sum of angles in a triangle is 180deg. As we know 2 of the angles (90deg and 60deg) we need to subtract them from 180deg.

180-90-60 = 30

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

i those same problems in math and dont know how to do them
