Answer:
answer is 60
Step-by-step explanation:
180-(64+56)=180-120=60
Answer:
900 x 2
Step-by-step explanation:
Angles of the parallelogram which is given in the problem are:α = 49° + 17 °= 66°
β = 180° - 66° = 114°
x - length of the longest side of the parallelogram;
Use the Sine Law:x / sin 49° = 20/ sin 17°
x / 0.7547 = 20 / 0.2924
0.2924 x = 15.094
x = 15.094 : .2924
x = 51.62 is the longest side of the parallelogram.
Answer:
1)2(lb+bh+hl)
=2(17*12+12*8+8*17)
=2(204+96+136)
=2*436
=872 in^2
2)2*pi*r(r+h)
=2*3.14*14(14+29)
=6.28*14(43)
=6.28*14*43
=3780.56 mm^2
3)A=11*4.3+3*6 +3*8+11*3(Area of each plane figure -triangle and rectangle)
=47.3+18+24+33
=122.3cm^3
4)h*(sum of II sides)+14*8+19*8+14*8+25(Area of plane surface-trapezium,rectangle,square)
=12.1(19+5)+112+152+112+25
=12.1*24+401
=290.4+401
=691.4ft^2
