area of first triangle =1/2×112×202×sin30°

1/2×112×202×1/2
5656m²

area of second circle=1/2×202×197×sin60.5°

1/2×202×197×0.870

Find the value of x.

galina1969 [7]

Answer:

x=15

Step-by-step explanation:

So we know 4x plus 8x gets a total of 180 degrees (since a straight line is 180 degrees). Combine 4x and 8x to get 12x. To find x, divide 12 from 180. 180/12 is 15.
