Answer:
114 cm²
Step-by-step explanation:
Area of shaded region
= area of circle -area of square
Given that radius= 10cm, r= 10cm.
Let the length of a side of the square be x cm.
Applying Pythagoras Theorem,
10² +10²= x²
100 +100= x²
x²= 200
Area of square
= x²
= 200cm²
Area of shaded region
= 3.14(10²) -200
= 3.14(100) -200
= 314 -200
= 114 cm²

Answer:
1.5
Step-by-step explanation:
225° bisects Q III
315° bisects Q IV
-270° = 90°
405° = 45° bisects Q I
cos(225) sin(315) + sin( –270) tan(405) = ?
(-½√2)(-½√2) + 1(1) = ?
0.5 + 1 = 1.5
A + B + C = 180
x + 2x + 2 + 3x + 4 = 180
6x + 6 = 180
6x = 174
x = 29
