Answer 1

Answer:

$\blue{ \bigstar} \huge \boxed{ \fcolorbox{white}{blue}{answer}}$

Step-by-step explanation:

Let us give name in the triangle to see the name please refer to the attachment

In /\ ABC,

\_BAC=\_EAF [Vertically opposite angles are equal]

=>Y=60° [Putting the value of an angle]

We know sum of 3 angles of a triangle 180°

Now, y=60°

Now in triangle 3 sides are X, X, and Y

Where we already have got y

Now,

X+X+Y=180°

=>2X+y =180°

=>2X=180°-60°

=>2X=120°

=>X=120°/2

=>X=60°

So, X=60°

Y=60°

Two angles are x and one angle y

Know more!

We know sum of 3 angles of a triangle is 180°

So, see X=60°

Y=60°

There are 2 X so X be 2 times of 60°

So, 60°+60°+60°=180°

So, hence verified ✅✅

Answer 2

$\huge\bf{Question}$

Find the value of x and y.

Figure in attachment.

$\huge\bf{Answer}$

Give name to angles of triangle (See in attachment)

In triangle ABC,

∠ABC = ∠ACB = x (Given)

∠MAN = ∠BAC = 60° (Vertically opposite angles are equal)

We know,

Sum of all angles of triangle is 180°

Now,

∠ABC + ∠BCA + ∠CAB = 180°

x + x + y = 180°

2x + 60° = 180°

2x = 180° - 60°

2x = 120°

x = 120/2

$\fbox \green {x = 60°}$

So, ∠ABC = ∠ACB = 60°

∠BAC = 60°

More Knowledge:-

In this question all angles of triangle ABC is 60°

Means, triangle ABC is an equilateral triangle.

Sum of all angles of any triangle is 180°

In this question we know all angles are 60°

60° + 60° + 60° = 180°

Hence, Proved

Hope this will be helpfull :)
