Answer:
angle 4 and angle 8
angle 3 and angle 5
Step-by-step explanation: the pair of angles on one side of the transversal and inside the two lines are called the consecutive interior angles
so, angle 4 and angle 8
and angle 3 and angle 5
are consecutive interior angles.
Answer:
ii) curved surface area =2 pie rh
2*22/7*14*21
1548 cm2
iii) total surface area=2 pie r(r+h)
2*22/7*14(14+21)
2780
iv) volume of cylinder=pie r2h
22/7*14*14*21

Step-by-step explanation:
Answer:
AC = 10sin40°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin40° = 
= 
, then
sin40° = 
( multiply both sides by 10 )
10sin40° = AC
