Are triangles DEF and LNM similar if LN equals 4, MN equals 3, DE equals 12, and FE equals 9?
nordsb [41]

Answer:

A

Step-by-step explanation:

DE corrsponding to the LN, EF corrsponding to the MN, and LN:DE=MN:FE=3

and angel N is corrsponding to the angle E,so it 's SAS.

Find the Total Surface area of a Pyramid. Its base is a regular hexagon 4cm on a side. its height is 8 cm. Round off to nearest
oksano4ka [1.4K]

Answer:

The total surface area of a regular hexagonal pyramid is 146.2 cm².

Step-by-step explanation:

The base is a regular hexagon 4cm on a side. its height is 8 cm.

The total surface area of a pyramid with regular hexagon base

A=\frac{3\sqrt{3}}{2}a^2+3a\sqrt{h^2+\frac{3a^2}{4}

Where, a represents the base edge and h represents the height of the pyramid.

The area of given regular hexagonal pyramid is

A=\frac{3\sqrt{3}}{2}(4)^2+3(4)\sqrt{(8)^2+\frac{3(4)^2}{4}

A=\frac{3\sqrt{3}}{2}(16)+12\sqrt{64+12}

A=24\sqrt{3}+12\sqrt{76}

A=146.182794027

A=146.2

The total surface area of a regular hexagonal pyramid is 146.2 cm².

Prove this trigonometric equation;<br><br> - tan^2x + sec^2x = 1,
alekssr [168]
Hey there :)

- tan²x + sec²x = 1    or    1 + tan²x = sec²x

sin²x + cos²x = 1 
Divide the whole by cos²x

\frac{sin^2x}{cos^2x} + \frac{cos^2x}{cos^2x} = \frac{1}{cos^2x}

\frac{sinx}{cosx} = tanx so \frac{sin^2x}{cos^2x} = tan^2x
and
\frac{1}{cosx} = secx so \frac{1}{cos^2x} = sec^2x

Therefore,
tan²x + 1 = sec²x
Take tan²x to the other side {You will have the same answer}

1 = - tan²x = sec²x or sec²x - tanx = 1
