Question

Hi guys can anyone answer this question fo 15 points pls quickly

Answer 1

Answer:

18 degrees

Explanation:

In the given figure, there's a right angled triangle with angles 3x, 2x and the third one would be 90°

According to the angle sum property,

→ 3x + 2x + 90° = 180°

→ 5x + 90° = 180°

→ 5x = 180° - 90°

→ 5x = 90°

→ x = 18°

∴ Required answer: 18 degrees

_____________________

Angle sum property of a triangle says that, sum of all its interior angles equals to 180°.

Answer 2

Question :-

• From the above figure, find the value of x .

Answer :-

• Value of x = 18° .

Explanation :-

• In the above figure, the angles are given 3x , 2x . And the third angle will be 90° .

∴ By using Angle Sum Property :-

➳ 3x + 2x + 90° = 180°

➳ 5x + 90° = 180°

➳ 5x = 180° - 90°

➳ 5x = 90°

➳ x = 90 / 5

➳ x = 18°

Hence :-

• Value of x = 18° .
