Question

Anyone can please explain these questions who will answer correctly ill follow them and mark as brainliest....!!!​

Answer 1

the first problem is based on the angle sum property

which states that the sum of all the angles in a triangle is equal to 180°

so in the first one we need to find the value of x

so apply the Angle sum property

which is angle A+ angle B+angle C =180°

A and C values are given,and in the B place substitute x itself

..25+x+30=180°

55+x=180°

x=180° - 55°

so x= 125°

hence we got the B value=125°

I am very sorry

I won't be able to answer the 2nd one

hope the 1st explanation helped you☺️☺️⭐️❤️❤️

Answer 2

Answer:

Ok...

So, In Angle Sum Property, the sum of all the angles of all the triangles is 180°

In the first question, we have 2 angles and need to find out the 3rd one.

Hence we can assume that the third angle is x.

25° + 30° + x = 180°

55° + x = 180°

x = 180° - 55°

x = 125°

A triangle in which two sides are equal is called an isosceles triangle.

As the angles are also equal, we can find out the other equal angle if we know the first one.

2x + 7 = 45°

2x = 45° - 7

2x = 38°

x = 38°/2

x = 19°

Hope it helps
