Answer:
243cm^3
Step-by-step explanation:
By Pythagoras' Theorem,
height of the prism ^2 + 5.4^2 = 7.8^2
height of the prism = ±√(7.8^2 -5.4^2) = ±5.6285cm (5s.f.) (rej. - 5.6285 since height > 0cm)
volume of the prism = 1/2 x 5.4 x 5.6285 x 16 = 243cm^3 (3s.f.)
This is a question on mensuration. If you wish to venture further into it/understand this topic better, you may want to follow my Instagram account (learntionary), where I post some of my own notes on certain topics and also some tips that may be useful to you :)
(Step#1): Find the Perpendicular bisector of a line segment with endpoints
(Step#2): Find a Point on the perpendicular bisector
(Which is the midpoint of a given line segment)
Using the midpoint Formula which is:
(X3, Y3) = (X1 +X22, Y1 + Y22)
I Hope this helps you!!!
Let θ = m∡I
tan θ = 20/21
tan⁻¹ (20/21) = θ
θ ≈ 43.60° or if you need to round to another decimal point, plug the equation I put in bold into a calculator.
<span> y = |x-2|+4
it is a negative 2 because you do the inverse</span>
