    sin30+cos60 = 1.

    Step-by-step explanation:

    Use the right angles triangle with angles 90-8=60-30.

    The hypotenuse = 2 and the 2 legs have values of 1 and √3.

    The 30 degree angle is opposite the leg of measure 1.

    sin 30 = opposite / hypotenuse 1/2 and cos 60 = adjacent / hypotenuse 1/2 so the sum is 1.
