Question 993800: Wright and solve an equation to find the value of x for a triangle with angles of 30 63 and 2x+7

a triangle always has 180 degrees.
the other angles make up 93degrees (63+30), so to determine the angle x set the equation equal to 180-93 like so:
2x+%2B+7+=+180-63-30
2x+=+180-63-30-7
x+=+%2880%2F2%29
x+=+40
therefore angle x = 40 degrees
