well, is noteworthy that an x-intercept is when y = 0 or namely is a solution or root of the quadratic, so we know then that the x-intercepts or solutions are at (-1,0) and (3,0), that simply means that

Answer:
x is equal to 20 in this picture.
Step-by-step explanation:
In order to find this, we need to note that these two angles will be equal to each other. Now we can put their values equal to each other and solve for x.
3x + 50 = 6x - 10
50 = 3x - 10
60 = 3x
20 = x
