Answer 1

Answer:

IN THE 1. QUESTION

X = 60

Y= 60

2. QUESTION

X = 45

Y = 45

3. QUESTION

X = 44

Y = 44

PLEASE MARK AS THE BRAINLIEST

Answer 2

(i)

By Linear Pair, third angle = 180-120 = 60

We know the bottom two angles are equal (angles opposite equal sides are equal)

Therefore, <y = third angle = 60*

Now, by angle sum property,

<x = 180 - (60+60)

<x = 60

So, <x = 60, <y = 60

(ii)

It is a right isosceles triangle, so we know <x = third angle

And by angle sum property, 180- 90 = 2(<x)

90 = 2(<x)

<x = 45

Now, by linear pair, <y = 180-45

<y = 135

So, <x = 45, <y = 135

(iii)

By opposite angles, topmost angle of triangle = 92

And opposite angles to opposite sides are equal, so <x = third angle

By angle sum, 180-92 = 2(<x)

2(<x) = 88

<x = 44

Now, by linear pair 180-44 = <y

<y = 136

So, <x = 44 and <y = 136

Hope this Helped!
