The first one is correct, just match the numbers with the corresponding sides of each triangle
Answer:
c'est une pyramide régulière à base carrée de35.4 m de large et de 21.6 m de haut. calculer l'inclinaison d'une face par rapport à l'horizontale. ... dans le triangle rectangle SHA: tg SAH = 21,6/17,7 donc l'angle SAH = 50,66° ...
Step-by-step explanation:
Answer:
x= 60°, y = 80°, z = 40°
Step-by-step explanation:
Look at the line substending 40° and Z°; you would see that both lines are parallel and so their angles are they the same.
Hence z= 40° { corresponding angles of parallel lines}
Similarly;
Look at the line substending 60° and x°; you would see that both lines are parallel and so their angles are they the same.
60° = x° { corresponding angles of parallel lines}
Now looking at the angle between x and y; let's call the angle between them r
And you would observe closely that r = z° = 40°{ vertically opposite angles are equal}
Note that x + r + y = 180°{ angle on a straight line}
y = 180° - ( x + r)
y = 180 - (60+40)
y = 180° - 100°
= 80°
Answer:
your answer would be 520
Step-by-step explanation:
13 x 40 = 520
We have been given that an employee shreds 341 pages in 11 minutes of work.
First of all we will divide 341 by 11 to find number of pages shred by employee in one minute.
Now let us multiply 31 by 20 to find number of pages shred by employee in 20 minutes.
Therefore, employee will shred 620 pages in 20 minutes.
