Question

The measure of the three angles of a quadrilateral are 650,750 and 850. The measure of fourth angle is​

Answer 1

Answer:

your values are wrong correct values is 65,75, and 85 because some of all four angles of a quadrilateral is 360, and ur values are greater than 360

Step-by-step explanation:

let 4th Angle = a

the sum of the angles of quadrilateral = 360

=> 65+75+85+a = 360

=> 225+a = 360

=> a = 360-225 = 135

Answer 2

Answer:

Given :-

• The measure of the three angles of a quadrilateral are 65°, 75° and 85°

To Find :-

• What is the measure of the fourth angles of a quadrilateral.

Solution :-

Let,

➲ Fourth Angle Of A Quadrilateral = x

As we know that :

★ Sum Of All Angles Of Quadrilateral = 360° ★

According to the question by using the formula we get,

⇒ 65° + 75° + 85° + x = 360°

⇒ 140° + 85° + x = 360°

⇒ 225° + x = 360°

⇒ x = 360° - 225°

➦ x = 135°

∴ The measure of the fourth angles of a quadrilateral is 135°.

✪ VERIFICATION ✪

↦ 65° + 75° + 85° + x = 360°

By putting x = 135° we get,

↦ 65° + 75° + 85° + 135° = 360°

↦ 140° + 220° = 360°

➲ 360° = 360°

Hence, Verified.
