The ratio of the measures of the three angles in a triangle is 2: 9: 4. find the measures of the angels

Qrst is a parallelogram. determine the measure of ∠q pls

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte
