Question

solve this Q please ​

Answer 1

Answer:

<B= 65° and <C= 65° (as AB=AC)

Step-by-step explanation:

So, both the A are cut from both sides and remaing that is left is B=C.

So, we have to mark the angle B and angle C in the triangle as 'x'.

So, x°+x°+50°=180°

2x°+50°=180° According to the transposing method of Algebra

2x°=180°-50°

=> 2x°= 130°

=> 2x/2 = 130/2

= x°= 65°

Hence, <B is 65° and <C is 65°

Answer 2

Answer:

Triangle ABC is an isosceles triangle because the two sides are equal that is AB = AC . A = 50°

so isosceles triangle the angle opposite to equal sides are equal

so , B = C

the C can be written as B

now by angle sum property

A+B+C = 180

A+B+B = 180

A+B2 = 180 2B = 180-50

2B = 130

B = 65

So , C = 65

Therefore B = 65 and C = 65
