are in the ratio 4.5. Find these angles.
In a
Find the unknown angles X and y
A​

Answer 1

Step-by-step explanation:

Let the angles be 4x and 5x

Now their sum is 90

 

4x+5x=90  

 

⇒9x=90  

 

⇒x=10  

 

So the angles are

4×10  

=40  

 

5×10  

=50  

Answer 2

Answer:

40 degrees and 50 degrees

Step-by-step explanation:

Sum of three angles of triangle = 180 degrees

It is right angle so one angle = 90 degrees

So angles , 90 + sum of two angles = 180

Sum of two angles  = 180-90 = 90

sum of two angles = 90

Now two other angles are in the ratio 4:5

So 4x+ 5x = 90

9x = 90

x = 10

So other two angles will be 4x = 40 and 5x = 50
