Question

pls help me with this sum plssss​

Answer 1

Question :-

In ∆ABC, AB = AC and ∠A : ∠B = 4 : 3. Find the measure of ∠C.

Answer :-

In a triangle,

If two sides are equal then angles opposite to them are equal.

Here, AB = AC

So, ∠B = ∠C

Let the ∠A be 4x

∠B = 3x

Also, ∠C = 3x

Using angle sum property of triangle :-

→ ∠A + ∠B + ∠C = 180°

→ 4x + 3x + 3x = 180

→ 10x = 180

→ x = 180/10

→ x = 18

∠C = 18 × 3 = 54

Value of ∠C = 54°

Answer 2

Answer:

write answer by yourself.

Step-by-step explanation:

if AB = AC & A : B =4:3

let A= 4x & B= 3x

then 4x+3x =180

then 7x=180

then 180/7=x

then then find the value of c by angle sum property.
