Question

2. Find the values of the unknowns x and y in the following diagrams:
​

Answer 1

Step-by-step explanation:

1) x = 70 y = 60

2) x= 50 y = 80

3) x = 110 y = 70

Answer 2

Step-by-step explanation:

Qsn.i

we know that 50+x=120

So,x=120-50=70

Then,50+x+y=180(we know that the sum of angles in triangles is eual to 180°)

so,60+70+y=180

130+y=180

y=180-130

y=50

Qsn.ii

y=80

50+x+y=180

50+x+80=180

x+130=180

x=180-130=50

Qsn.iii

x=50+60=110

y+50+60=180

Y+110=180

y=180-110

y=70
