Answer:

3. m∠1 = 106° ~ this is because ∠1 and ∠2 together make a straight line and are therefore supplementary, meaning added together, they equal 180° (so I did 180° - 74° = 106°)

4. m∠3 = 74° ~ again, it is supplementary to ∠1. It is also equal to ∠2

5. m∠8 = 114° ~ angles opposite of each other (like 1 and 4) are equal (as we know from question 4). From there, we can use the corresponding angle theorem, so we know 4 and 8 are congruent. (also you can just know 1 and 8 are congruent by using the opposite exterior angles theorem)

6. m∠6 = 124° ~ using same-side interior angle theorem, they are supplementary angles (or the corresponding angles theorem mentioned above, make 4 congruent to 8, and 8 is supplementary to 6)

7. m∠7 = 96° ~ using same side exterior angle theorem, these angles are supplementary

8. m∠2 = 64° ~ again, same side exterior angle theorem

The value of m∠M is 112°

Step-by-step explanation:

In the parallelogram NPMQ, opposite angles ∠P=∠M.

To get the value of the angles, equate the two expressions;

(6x-2)°=(4x+36)°

6x-2=4x+36 ------ collect like terms

6x-4x=36+2

2x=38

x=38/2 =19

So, ∠M= (6x-2)° = (6×19 - 2)° = 112°
