Answer:The lateral surface area Al of the triangular prism is 270cm^2
Step-by-step explanation:
An equilateral triangle has all 3 sides equal = 6 cm each
The height of the container is 15cm
Lateral surface area,Al =(a + b + c)h
Al= (6+6+6)15
Al= (18)15 = 270cm^2
X + y, because you do x + y and you can't simplify. Hope this helps!
Answer:
Step-by-step explanation:
p=sec0+tan0
=1/cos0 + sin0/cos0
=(1+sin0)/cos0
square both sides
(1+sin)^2 /cos^2 = p^2
(1+sin)^2/(1 - sin^2 ) = p^2
(1+sin)^2/((1-sin)(1+sin)) = p^2
(1+sin)/(1-sin)=p^2
1+sin=p^2-p^sin
sin+p^2sin=p^2-1
sin(1+p^2)=(p^2-1)
sin=(1-p^2)/(1+p^2)
cosec=1/sin
=(1+p^2)/(1-p^2)
I would say the answer is B. 8 1/2 because 11/20 is close to 10/20 which would be the same as 1/2
