Area = the top semicircle + the rectangle AEBD
= 1/2 pi*6^2 + 6*12 = 128.55 cm^2 to nearest 100th
Perimeter = 6pi + 12 + 2 pi * 3 = 49.70 cm
Answer:
360°
Step-by-step explanation:
Each of the two triangles have 3 angles that add up to 180°.
So,
180° + 180° = 360°
The sum of the angles of a quadrilateral is 360°
Answer:
2 (length +breadth)
Step-by-step explanation:
2(2x+3) (x+1)
Multiply two on both sides and solve it
Step-by-step explanation:
According to the given diagram,
By exterior angle property,
x=46°+30°
x=76°
I think its the first one (x+5,y+6)
