A triangle has three angles that measure 30 degrees, 70 degrees What is the value of x?

x = 80

Step-by-step explanation:

Sum of all the angles of triangle = 180

30 + 70 + x = 180

       100 + x = 180        {Subtract 100 from both sides}

                x =  180 - 100

                x = 80°

step-by-step explanation:

5×5×5+2(8)÷2(2)+3(3)

15+16÷4+9

31÷13

do 31÷13 and u will get ur answer

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
