Question

solve unknown angles​

Answer 1

$\longrightarrow$ If In Given Traingle Two Sides Are Equal Then The Opposite Angle Of 80° Must Be Same As Another Angle

$\longrightarrow$ Hence, We Can Write It Like This,

a = b

$\longrightarrow$ Now, We Can Solve All Angles,

$\longrightarrow$ We Know That, In Traingle, Sum Of All Angles Is 180°

so,

$\longrightarrow$ 80° + a + b = 180°

$\longrightarrow$ Now, We Have Already Find Out that, a = b

so,

• 80° + a + a = 180°

• 2a = 180° - 80°

• 2a = 100°

• a = $\sf \frac{100°}{2}$

• a = 50°

Now, we know a = b

if a = 50° then also b = 50°

So For x

• x + b = 180°
• x + 50° = 180°
• x = 180° - 50°
• x = 130°

Now, For y

• y + a = 180°
• y + 50° = 180°
• y = 130°

Hence

• x = 130°
• y = 130°
• a = 50°
• b = 50°

I hope it helps you ❤️✔️
