Question

the sum of two acute angle=70 & difference between the two is 10.find the traingle​

Answer 1

Step-by-step explanation:

Let the two angles be x and y respectively

ATQ,

x + y = 70.....(1)

And

x - y = 10......(2)

From (1) and (2) we get,

2y = 60

y = 30

Put the value of y in 1

x + 30 = 70

x = 70 - 30

x = 40

By angle sum property

40 + 30 + 3rd angle = 180

3rd angle = 110°

Since all angles are different

Therefore,

It is a scalene triangle.
