PLS HELPP ITS URGENT Find the missing angle and name the other three given angle.

PQR=___

Name:_
_
_

Step-by-step explanation:

The angles between the parallel sides add up to 180 degrees.

So 180-70 = 110 degrees.

Let,

The unknown angle measure be x°.

We know that,

Sum of all angles of a Quadrilateral measures 360°.

So,

=> ∠QPR + ∠PSR + ∠SRQ + ∠RQP = 360°

=> 120° + 60° + 70° + x° = 360°

=> 180° + 70° + x° = 360°

=> 250° + x° = 360°

=> x° = 360° - 250°

=> x° = 110°

Therefore, the names of the angles & their values will be,

=> ∠QPR = 120°

=> ∠PSR = 60°

=> ∠SRQ = 70°

=> ∠RQP = 110°

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
