Don't understand the measure

Answer 1

Answer: Hello,

$\widehat{ABD}=(180-40)/(2)$ =70 (sum of angles of a triangle=180°)

$\widehat{ABE}=180-70=110$ supplementary angles

$\widehat{ABE}=\widehat{DCF}$ translation BC

$\widehat{BCF}=110-40=70$ image of the angle DAB by the axis symmetry DB

$\widehat{BCF}=\widehat{BEF}$ opposed angles of a parallelogram
are supplementary.

$\widehat{BEF}=\widehat{HEG}$ opposed angles by the vertex

$\widehat{HEG}=\widehat{IHE}=70$ alterne-interne angles (sorry for the words English is difficult for me)

If two lines are perpendicular, then they form:

Answers

If two lines are perpendicular, they form a 90° angle, or a right angle. By definition, two perpendicular lines intersect at a right angle. For instance, a vertical line and a horizontal line will cross at a 90° angle.

You have 1 case of soap bars and there are 150 bars in a case. You use 300 bars of soap per day. How many cases do you need to order to have enough for 7 days?* 11 12 13 14

Answers

You first multiply 7*150 and that is 2100 bars of soaps you need to last 7 days. If there is 150 bars in each case you divide 2100 by 150 and you get 14?. You are using 14 cases for 7 day.
