Answer:
18 square units.
Step-by-step explanation:
In this problem, we are asked to give an expression that can be used to mentally multiply 6 and 198. In order not to go through the rigorous multiplication, we can estimate 198 to 200, that is 6 *200 equal to 1200. Since there is a 2*6 excess or 12 then we subtract: 1200 -12 equal to 1188.
Answer:
66° by adding up 75° and 39°, we get 114°.
since all triangles equal 180°, 180° minus 114° is 66°
