Answer:
Step-by-step explanation:
It is simply the sumation of a triangle and a rectangle minus a half circle.
area triangle + area rectangle - area half circle = Total area
1/2( bh ) + bh - (π (d/2)²) / 2 = Total area
0.5(7)(6) + (10)(7) - (π (7/2)² ) / 2 = Total area cm²
21 + 70 - 19.24 = 71.76 cm²
Answer:
135
Step-by-step explanation:
if mK is 90 then mD is 60 and mS is 30. since the new point is in the middle of the triangle divide 60 and 30 by 2. Now mD is 30 and Ms is 15 so 30+15=45 so 180-45=135
