respectively. Wrtie the measurement of the 4th angle

Answer 1

Answer:

Answer is in above Picture

Answer 2

★ Given :-

• Angles = 100° , 62° , 78°

⠀⠀⠀⠀⠀⠀⠀

★ To Find :-

• Measurement of the 4ᵗʰ Angle = ?

⠀⠀⠀⠀⠀⠀⠀

★ Solution :-

⠀⠀⠀⠀⠀⠀⠀

∓ Here, it is given that, Measurement of the three angles of a Quadrilateral are 100° , 62° , 78° . And, we have to find Measurement of the 4ᵗʰ Angle .

⠀⠀⠀⠀⠀⠀⠀

• Now, let's solve step by step -----

⠀⠀⠀⠀⠀⠀⠀

◆ As we know,

• The sum of all angles of a Quadrilateral is 360° .⠀⠀⠀⠀⠀⠀⠀

∴ According to the question :-

⠀⠀⠀⠀⠀⠀⠀

● 100° + 62° + 78° + x = 360°

➳ 240° + x = 360°

➳ x = 360° - 240°

➳ x = 120°

⠀⠀⠀⠀⠀⠀⠀

★ Hence :-

• Measurement of 4ᵗʰ Angle = 120° .
