1/sin10°-√3/cos10°=4

Alexandra [31]

Answer:

$\frac{1}{\sin \left(10^{\circ \:\:}\right)}\:\:\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=4$

Step-by-step explanation:

Given the expression

$\frac{1}{\sin \left(10^{\circ \:}\right)}-\frac{\sqrt{3}}{\cos \left(10^{\circ \:}\right)}=4$

Taking the left-hand side and solving it

$\frac{1}{\sin \left(10^{\circ \:}\right)}-\frac{\sqrt{3}}{\cos \left(10^{\circ \:}\right)}$

$\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=5.76$

and

$\frac{\sqrt{3}}{\cos \left(10^{\circ \:\:}\right)}=1.76$

so the expression becomes

$\frac{1}{\sin \left(10^{\circ \:\:}\right)}\:\:\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=5.76-1.76$

$=4$

Thus, we conclude that

$\frac{1}{\sin \left(10^{\circ \:\:}\right)}\:\:\frac{1}{\sin \:\left(10^{\circ \:\:}\right)}=4$

Two points A and B are on opposite sides of a building. A surveyor selects a third point C to place a transit. Point C is 52 fee

alexdok [17]

Answer:

Step-by-step explanation:1.

Use law of cosine.

AB^2 = AC^2 + BC^2 - 2 * AC * BC * cos(angle ACB)

AB^2 = 53^2 + 71^2 - 2(53)(71)cos(53)

Using calculator,

AB = about 57.6259 feet

Law of cosine again.

d^2 = 400^2 + 90^2 - 2(400)(90)cos(45)

using calculator,

d = about 342.3278 feet
