Question

traingel are 45 ,32 degree find the 3rs angle of a traingel​

Answer 1

Answer:

What is a triangle?

➾ A triangle is a plane figure with three sides and three angles. There are 6 types of triangles. They are as follows :-

1] Acute - angled triangle : A triangle whose measure is less than 90°

2] Right - angled triangle : A triangle whose measure is exactly 90°

3] Obtuse - angled triangle : A triangle whkse measure is more than 90°

4] Equilateral triangle : A triangle whose all three sides are of same length.

5] Isosceles triangle : A triangle whose two sides are of same length and one side is of different length.

6] Scalene triangle : A triangle whkse all three sides are of different lengths.

Coming to your question :

Given, two angles of a triangle are 30° and 45°

To find, third angle

So, let the third angle be x

Sum of all interior angles of a triangle is 180°

According to the question,

30 + 45 + x = 180

➾ 75 + x = 180

➾ x = 180 - 75

➾ x = 105

∴ The third angle is of \orange{\boxed{\red{105{^\circ}}}}

105

∘

∴ The angles of the triangle are 45°, 30° and 70°

Answer 2

The measure of third angle will be 103degree. By applying the angle sun property of a triangle.
