Answer:
26
Step-by-step explanation:
The triangle equals 180 degrees the two measurements we already have is 90 degrees (the right angle) and 64 degrees.
90+64=154 and 180-154=26.
So 26 is your answer because 90+64+26=180
Hope this helps!
Planes X and Y are perpendicular to each other
Points A, E, F, and G are points only in plane X
Points R and S are points in both planes X and Y
Lines EA and FG are parallel
The lines which could be perpendicular to RS are EA and FG.
(a is the length of the side of each edge of the cube)<span>In words, the surface area of a cube is the area of the six squares that cover it. The area of one of them is a*a, or a<span> 2</span> . Since these are all the same, you can multiply one of them by six, so the surface area of a cube is 6 times one of the sides squared.</span>
Answer:
<em>The size of the sample 'n' = 2401</em>
Step-by-step explanation:
<u><em>Step:1</em></u>
Given that the margin of error = 2 % = 0.02
The margin of error is determined by
we know that the proportion
<u><em>Step:2</em></u>
<em>The margin of error is determined by </em>
<em> </em><em></em>
√n = 49
Squaring on both sides, we get
n = 49 × 49
n = 2401
<u>Final answer:-</u>
<em>The size of the sample 'n' = 2401 </em>
