Answer 1

180-38 = 142

Answer 2

Thats it ? @helpme1.2

Answer 3

a rectangle has 360 degree in over all
so in the drawing, you can tell that 2 of the angles have similar measurement, and the other 2 has the same measurement
<JML has different measurement than <JLM = 38
so the other angle must be 142
Make sense?

Answer 4

38+38+142+142 = 360

Answer 5

Yes! I get it Thanks! @helpme1.2
Help me with another one?

Answer 6

yeah

Answer 7

The isosceles trapezoid is part of an isosceles triangle with a 34 degree angle. What is the measure of an acute base angle of the trapezoid? Of an obtuse base angle? The diagram is not drawn to scale.

Answer 9

I don't want just the answer I would like to learn how to.

Answer 10

well as you u a triangle always has a measurement of 180 degree, so
acute angles are the ones below 90 degrees
obtuse angles are the one above 90 degrees-180
2x + 34 = 180
x = 73

180 - x
180-73 = 107

Answer 11

Where did you get 2x ? and why did you choose 34 ?

Answer 12

well 34 is a given degree
we chose 2 to find the acute angles since 2 acute angles = 180

Answer 13

Oh okay, Thanks allot! You really earned my Medal, Good testimonial, and Fan! Thanks for being patient!

Answer 14

in a triangle 2 acute angles + the given degree (which in this case 34) = 180

Answer 15

No problem
