Idon't get this, is it 180° because of the straight line? and if it is what would the angles be for the rest?

Don't listen to that other guy. He's just guessing.

M<1=112

Reasoning: The straight line represents a 180° Angle, and subtracting the excess 68° from the other angle results in a total of 112° for the opposite angle

M<5=90°

Reasoning: The square on the corner of the angle indicates that it is, in fact, a right angle. All right angles are 90°.

Now there is a reason I put 5 before the others

M<3=68°

Reasoning: It is opposite of the other 68° Angle, and if you notice, it lines up perfectly with the intersecting lines.

M<4=22

Reasoning: By taking the 180° Angle, and subtracting the 90° Right angle and the 68° Angle, the resulting number is 22.

I hope this helped!

Thanks!

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
