please help me with this question in mathematics .....



please help ​

Answer 1

Step-by-step explanation:

a+b = 90°

2x+3x = 90

5x = 90

x = 18

b = 3x = 3×18 = 54°

• Now b + c = 180
• => 54° +c = 180°
• => c = 126°

Answer 2

Answer:

Let a:b be 2x:3x

Now , let c be x

So total summation is 360 degree

and also o =90 degree

So 2x+3x+x = 360-90

or 6x = 270

or x = 26

Thus c = 26 degree..
