Question

The two acute angles of an obtuse angled triangle , whose obtuse angle mesurers 131 degree are in the ratio 2 : 5 find the angles

Answer 1

Answer:

Step-by-step explanation:

Let two acute angles be 2x and 5x.

Sum of all angles in triangle is 180.

So,131+2x+5x=180

131+7x=180

7x=49

x=7

So,2x=14

&5x=35

So three angles are 14,35 and 131

Answer 2

Step-by-step explanation:

Let the two acute angle be x

first acute angle = 2x

second acute angle = 5x

obuutuse angle measure = 131 degree

Sum of the triangle = 180 degree

so, 131+2x+5x = 180

7x = 180-131

x = 49/7 = 7

Now, 2x = 7*2 = 14

5x = 7*5 = 35

so, two acute angle = 14,35.
