Question

Find the measure of the missing angles.

Answer 1

Answer:

Angle D = 90°

Angle E= 80°

Angle F = 100°

Step-by-step explanation:

$d = 90$

Why??

We see that d and it's adjacent angle is supplementary i.e. forms an angle of 180°.

So therefore

$d + 90= 180$

$= > d = 180 - 90$

$= > d = 90$

Answer :- d = 90°

___________________________________________________

$e = 80$

Why??

In the digram we see that 80° and angle e are vertically opposite to each other and we know that vertically opposite angles are same ,

So therefore

Answer :- e= 80°

$f = 100$

Why??

We see that both e and f are supplementary i.e. 180°.

Therefore,

$f + e = 180$

$= > f + 80 = 180$

$= > f = 180 - 80$

$= > f = 100$

Answer :- angle f = 100°
