In ΔDEF, the measure of ∠F=90°, DE = 70 feet, and EF = 57 feet. Find the measure of ∠D to the nearest tenth of a degree.

kondor19780726 [428]

Answer:

54.5°

Step-by-step explanation:

You know that in a right triangle, the sine of an angle is given by ...

Sin = Opposite/Hypotenuse

sin(D) = EF/ED = 57/70

The inverse sine function is used to find the angle:

∠D = arcsin(57/70)

∠D ≈ 54.5°

Answer:

Length of base (a) = 5 units

Total Surface Area of Pyramid (T.S.A.) = ?

Now,

T.S.A. = Area of four triangles + Area of base

= $4(\frac{\sqrt{3} }{4})(5^{2}) + 5^{2} = 25\sqrt{3} + 25$ ≈ $68.301sq. units$

Find the perimeter of given figure:

Afina-wow [57]

Answer:

≈ 18 cm

Step-by-step explanation:

1. Find the length of half a circle of radius 3.5 cm:

$\tt \cfrac{C}{2}= \cfrac{2\pi r}{2}=\pi r=3.14\cdot3.5=10.99 \ cm$

2. Find the length of the diameter:

D = 2r = 2 · 3.5 = 7 cm

3. Find the perimeter of the figure:

P = 10.99 + 7 = 17.99 ≈ 18 cm
