What is the measurement of the fourth angle of a quadrilateral ithe the others measure 80 degrees 120 degrees and 65 degrees?

360 - (80 + 120 + 65) ie 95o


What is the measurement of the fourth angle if a quadrilateral if the others measure 80 degrees 120 degrees and 65 degrees?

Sum of angles in a quadrilateral is 360° Three angles sum to 80° + 120° + 65° = 265° Therefore the missing fourth angle is 360° - 265° = 95°


What is the fourth angle of a quadrilateral if the others measure 82 degrees 78 and 90 degrees?

110 degrees.

What is the measurement of the fourth angle of a quadrilateral if the others measure 60 degrees 120 degrees and 90 degrees?

The answer would be 90 degrees, because the quadrilateral's angles should add up to 360 degrees. 360 - (60 + 120 + 90)= 90 120 + 60 = 180 + 90 = 270 + 90 = 360


Is a quadrilateral with one right angle necessarily a rectangle?

A quadrilateral can have two right angles and still not be a rectangle, if one side is oblique (neither right nor parallel) to the others, but three right angles force the fourth, and you have a rectangle.


Is vector the same as velocity?

No. A vector is any measurement where a direction is relevant. Velocity is one such measure, but there are others, unrelated to velocity (for instance, force).

Depends what sort of quadrilateral. For a square and rectangle, it's 90 all the way, but with all others, it varies.

What are things you can measure using kilometer?

You can measure and express any length or distance, no matter how large or small,in terms of kilometers. But when it comes time to write the measurement down,remember it, work with it, or tell others about it, it's often more convenient ...especially when 'kilometer' results in a very small or a very large number ... to convertthe measurement to a smaller unit, such as the nanometer, or a larger unit, such asthe light year.
