Answer:
x =29
x+6 =35
4x = 116
Step-by-step explanation:
The sum of the angles of a triangle is 180
x+ (4x) + (x+6) = 180
Combine like terms
6x+6 = 180
Subtract 6 from each side
6x+6-6 = 180-8
6x = 174
Divide each side by 6
6x/6 = 174/6
x =29
x+6 = 29+6 = 35
4x = 29*4 =116
We know that
[area of the figure]=[area of rectangle]+[area of semi circle]
area of rectangle=b*h------> 10*18-----> 180 cm²
area of semicircle=pi*r²/2
diameter=18 cm
radius=18/2----> 9 cm
area of semicircle=pi*9²/2-----> 127.17 cm²
[area of the figure]=[180]+[127.17]------> 307.17 cm²
round <span>to the nearest unit </span>------> 307 cm²
the answer is
the area of the figure is 307 cm²
