Answer 1

Question :

If one angle of a right triangle is 60°, what will be the third angle?

Answer :

$\sf\pink{Given}$

• It is right angled therefore its one angle will be 90°

• Its second angle is 60°

$\sf\pink{To\:Find}$

• Its third angle = ?

Explanation :

• let the third angle be "x"

Rule :

Sum of all angle of a triangle is 180°

$\longrightarrow\bf{90 + 60 + x = 180}$

$\longrightarrow\bf{150 + x = 180}$

$\longrightarrow\bf{x = 180 - 150}$

$\longrightarrow\bf\pink{x = 30}$

• Therefore the third angle is 30°
