Question

The angles of a triangle are 2x , x+25° and 3x + 5º. The triangle is
(A) scalene triangle
(B) right triangle
(C) equilateral triangle
(D) isosceles triangle​

Answer 1

Answer:

We get a triangle by joining the three non- collinear points A, B and C. (i) The side ... The angles of a triangle are in the ratio 1 : 3 : 5. ... In a right angle triangle, one of the angles is 90o.

Answer 2

Answer:

option D - Isosceles triangle

Step-by-step explanation:

we know that sum of angles in a triangle is 180 degrees...

so,

2x + x + 25 + 3x + 5 = 180

6x + 30 = 180

6x = 180 - 30

6x = 150

x = 25 degrees

2x = 2(25) = 50 degrees

x + 25 = 25 + 25 = 50 degrees

3x + 5 = 3(25) + 5 = 75 + 5 = 80 degrees

Given triangle is Isosceles triangle as two angles are equal....
