FIND THE THIRD ANGLE IN A TRANGLE IF TWO OF THE ANGLES ARE 43 AND 114

  • geometry -

    43 + 114 + x = 180

    Solve for x.

    Ms. Sue, I am not an expert but I know that the numbers all have to be on one side and the letter on the other

    Ex.
    43+114+X=180
    114+43=157
    157+X=180
    Do the opposite operation to get letter alone so it would be -157 on both sides..
    157+X=180
    -157+X=180-157
    X=23

    Hope that helps
