Question

1) T he angles of a traingle are in the ratio 2:3:5 , Then find the largest angle ?
2) One of acute angle of a right traingle is 40degree , Find the other acute angle ?

Answer 1

Answer:

1) => 90

2)=> 50

Step-by-step explanation:

1) => Suppose,

the angles are 2x, 3x and 5x

We have,

Sum of angles of triangle = 180

or, 2x+3x+5x = 180

or, x = 18

So, the largest angle = 5x = 5*18 = 90

2)=> Let, the unknown acute angle be x.

Sum of the angles of right angled triangle = 90

or, x + 40 = 90

or, x = 50

Therefore, the other acute angle is 50

Answer 2

Answer:

I know only of first one only

Step-by-step explanation:

first let the number be 2x,3x4x

Now, 2x+3x+4x =180°

9x=180°

x=180°/9

x=20

NOW- 2x=2×20=40

3x=3×20= 60

4x =4×20= 80

So , the largest angle is 4x=80
