Question

Take a card board and cut the following from it : (a) A scalene triangle with one obtuse angle. (B) A right_angled triangle with one angle measuring 30° . (C) An isoceles triangle with one angle measuring 120°.(D) An equilateral triangle with side length 4 cm. plz help​

Answer 1

Answer:

One of the angles of obtuse-angled isosceles triangle is 35

∘

, the other same angle will be 35

∘

.

Let the obtuse angle be x.

Thus, sum of angles of a triangle =180

+35

o

+x=180

o

x=110

∘

Therefore, the measure of each angle is: 35
