Question

An altitude of a triangle is five-thirds the length of its corresponding base. If the altitude be
increased by 4 cm and the base decreased by 2 cm, the area of the triangle remains the
same. Find the base and the altitude of the triangle.
of triangle are in the ratio 4: 5. If the sum of these anoles is .

Answer 1

Question:-

find the angles of triangles are in the ratio 4:5 if the sum of these angle is?

Answer:-

We know that the sum of angles of triangle is 180°

Lat ratio= 4x+5x

According to Question:-

4x+5x = 180°

9x = 180°

x = 180/9

x = 20°

First Angle = 4x = 4×20 = 80°

Second Angle = 5x = 5×20 = 100°
