<span>b. 60 m2
</span>Find the area of the figure. Assume all figures are made up of parallelograms and triangles.
NOT:
b. 60 m2
c. 108 m2
<span>d. 135 m2 please help</span>

so one: the middle Angles are all 90 degrees triangles equal 180, the angle opposite of "x" is equal to 34 so 180-90-34=x
two: both angles are equal set it up like an equation and solve for n
three: the corner angle of the right triangle is equal to 61 as well again do 180-(61×2)=x
4: do this equation (<ktu)2+ x = 180 then solve for x
5: not exactly.sure what its asking
hope this helps
Answer:
test statistic, z = −1.74
Step-by-step explanation:
given data
students n = 100
mean time x = 41.13 seconds
σ = 5
we consider µ = 42
solution
we get here The test statistic that is express as
test statistic, z =
......................1
put here value and we will get
test statistic, z = \frac{41.13-42}{\frac{5 }{\sqrt{100}}}
test statistic, z = −1.74
Answer:
15/17
Step-by-step explanation:
in the described scenario AB is the vertical leg of the right-angled triangle, that can be seen as the trigonometric triangle of the angle at C.
this triangle would be inscribed inside a circle with the center at C and the radius being BC.
the sine value of an angle is the length of the vertical leg of the trigonometric triangle inside the normed circle with radius 1.
if inside a larger circle, to get the sine value, these lengths must be scaled back to the norm of radius = 1.
and that is what the sine ratio is : the actual length of the vertical leg scaled to the radius of 1 (by dividing it by the actual radius) :
sin(theta) = AB / BC = 15/17
FYI
sin(theta) = 15/17 = 0.882352941...
and the angle theta is then 61.92751306...°
cos(theta) = CA / BC = 8/17 = 0.470588235...
and of course, this gives us the same angle.
Answer:
cos 60° isn't equivalent
Step-by-step explanation:
cos 60°=1/2
