Answer:
Step-by-step explanation:
sum of angles of parallelogram=360 degrees
adjacent angles add up to 180 degrees (supplementary angles)
Angle A=104 (DAB=104)
Angle D=180-104=76 degrees (angle ADB)
Angle B=60 degrees
Angle C=180-60=120 (DCB)
Answer:
B
Step-by-step explanation:
12.25 times 11 is 134.75
488 times 0.21 is 102.48
134.75 plus 102.48 equals 237.23
237.23 is closest to 232 which is B.
Answer:
A) 
Step-by-step explanation:
in a 30-60-90 triangle the sides, respectively, are in the ratio of 1 : : 2
C
length= 10 cm
width= 4 cm
height= 2 cm
10*4= 40
40*2= 80
If you put in a calculator 11^2+9^2 then square root that it should give you your answer
