According to the given data we have the following:
measure of three angels of a triangle are 43, 70, x
x?
The sum of the measures of the three angles of the triangle is 180
Therefore, to calculate the value of x we would have to make the following calculation:
43 + 70 + x = 180
113+ x=180
x=180-113
x=67
Therefore, the value of the angle of x would be 67
