Question

can anyone plsssss help me...... i am getting crazy with these sums.... plssssssssssssssssssssssssss

Answer 1

1.x=40(alternate interior angles)
40+75+y=180(angle sum property)
115+y=180
y=180-115
y=65
y-5
65-5
60
60+40+z=180
100+z=180
z=180-100
z=100
2.ΔABC and ΔABD are on same base AB and between same parallel BC and AD.
so,ar(ABC)=ar(ABD)
