Question

the base angles of a trapezium are 120 degree and 100 degree . find the other two angles....

pl solve it ....
pl give answer
​

Answer 1

answer ... if a trapizium ABCD having angles angle a ,angle b,angle c, angle d .

We know,

if angle c =120,d =100 then we know

here AB parellal to CD So,

here angle a+angle c= 180 so,

angle a = 180 -120=60

and angle b+ angle d = 180

so angle b = 180 - 100 = 80

therefore, another two angles are become 60, 80.....

if you not sure to this ans. is wrong then you can cheak , we know in case of trapizium the total of 4 angles always 360 degree.

angle a+angle b+ angle c+angle d = 360

60+80+120+100=360 prove..
