Answer:
<em>21(a) 8 cm</em>
<em>21(b) 1.6 cm/sec</em>
Step-by-step explanation:
21(a)
21 cm = 13 cm = 8 cm
21(b)
Increase in depth from 6 sec to 11 sec: 8 cm
Time from 6 sec to 11 sec: 11 sec - 6 sec = 5 sec
Rate = (8 cm)/(5 sec) = 1.6 cm/sec
The fifth angle is 108 degrees
<em><u>Solution:</u></em>
Given that a pentagon has angle of 104, 102, 115 and 111 We have to find the angle of fifth angle
A pentagon is a five sided polygon
The sum of all the interior angles of a pentagon is 540 degrees
Given that,
Angle 1 = 104
Angle 2 = 102
Angle 3 = 115
Angle 4 = 111
Angle 5 = ?
Let the angle be "x"
So to find the fifth angle, add all the angles and equate to 540 degrees
Angle 1 + Angle 2 + Angle 3 + Angle 4 + Angle 5 = 540
104 + 102 + 115 + 111 + x = 540
432 + x = 540
x = 540 - 432
x = 108
Thus the fifth angle is 108 degrees
Answer:
Opposite angles
Step-by-step explanation:
Where two lines intersect each other, the angles opposite to each other are opposite angles. Opposite angles have the same measure.
