Subject: geometryfind missing anglefind the measurement for a

straight line  angle =180 degree as we know

there are three angles in straight line means sum of all angles must = 180

 15+a+38=180

so   53+a=180

so   a=180-53

ans     a=127 degree

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
