Collect like terms and you'll get -2 - 3(a - b)
lateral area = 2 X pi X r X H
= 2 x 3.14 x 5 x 9 = 282.6
A triangles three angles always sum up to 180 degrees. We must find angle B.
We already have angle A and C, so it's quite simple.
Angle A is 28*, and angle C is 36*
We add these two together
28 + 36 = 64
Now we subtract
180 - 64 = 116
Angle B = 116*
Hope this helps you! (:

Answer:
Ram studied for longer time
Step-by-step explanation:
An hour = 60 minutes
Raj studied for 4/7 of an hour
= 4/7 of 60 minutes
= 4/7 × 60
= (4×60)/7
= 240/7
= 24.29 minutes
ram studied for 5/8 of an hour
= 5/8 of 60 minutes
= 5/8 × 60
= (5×60)/8
= 300/8
= 37.5 minutes
who studied for longer time?
Ram - Raj
= 37.5 - 24.29
= 13.21 minutes
Ram studied for longer time
Ram studied 13.21 minutes longer than Raj
