What do the angles of a triangle add up to? If 2 angles are 34 and 18, what is the third angle?

The third angle is 128 degrees

Step-by-step explanation:

The interior angles of a triangle add up to 180 degrees, therefore we can set up the equation x+34+18=180 to find the missing angle. Solving the equation gets us x=128

Angles of a triangle add up to 180 degrees. The third angle would be 128 degrees.

Step-by-step explanation:

34 + 18 = 52

180 - 52 = 128

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
