Area of the sector is 981.3 cm²
Step-by-step explanation:
- Step 1: Find the area of the sector where radius = 50 cm and central angle = 45°
Area of the sector = πr² (C/360), where r is radius and C is the central angle
⇒ Area = 3.14 × 50² × (45/360)
= 3.14 × 2500 × 1/8
= 7850/8 = 981.3 cm²
-2x+1/2y=18
xint is where y=0
-2x+0=18
-2x=18
divde by -2
x=-9
xint isi (-9,0)
Answer:
⦣ACD = 90º
Step-by-step explanation:
⦣ACD + ⦣BCD = 180º
⦣BCD = 90º
⦣ACD + 90º = 180º subtract 90º from both sides
⦣ACD = 90º
