Answer:

Yes, I agree with Yamini's statement that "xº, (x+10) and (x+20)° are three angles of an acute angled triangle."

Because,

Here are the reasons:

• In an acute-angled triangle, all three angles are less than 90 degrees.
• Let's assume the first angle is xº. Since x is a variable, it can take any value.
• The second angle is (x+10)°, which means it is 10 degrees greater than the first angle.
• The third angle is (x+20)°, which is 20 degrees greater than the first angle.
• As long as x is less than 70 degrees, the sum of these three angles will be less than 180 degrees, making it an acute-angled triangle.

Therefore, based on these reasons, I agree with her.
