Answer:
608 cm^2
Step-by-step explanation:
<em>Top and bottom rectangles: </em>
2(10*16)
= 2(160)
= 320
<em>Middle rectangle:</em>
(12*16)
= 192
<em>Two triangles:</em>
2((12*8)/2)
= 2(96/2)
= 96
<em>Surface area of the whole prism:</em>
320 + 192 +96
= 608
Answer:
42
Step-by-step explanation:
5/7x=30
x=42
Answer:
14
Step-by-step:
A triangle has 3 sides, 2 of which we know and need to use in this question, i.e, 8√7 and X (which we need to solve for).
X is opposite to that 45° angle, which makes it the "opposite" and the 8√7 is the "hypotenuse"
When solving questions like this one, remember the acronym SOH CAH TOA which means: sinσ =
cosσ =
tanσ =
NB: σ= the known angle
Well lets check it.
44 divided by 4 is 11.
11 - 5 is 6.
So yes you are correct.
