1/80

Step-by-step explanation:

-8*5*xy= -1

Sub 2 for x

-8*5*2*y= -1

-80y=-1

y=1/80

(i was kinda confused because i wasn't sure if the x was a variable or a multiplication symbol but i made it a variable) yea

A helicopter is hovering 110 feet in the air over a landing pad. If a man sees the helecopter at an angle of elevation of 29°, w

Pavel [41]

See the attached figure to better understand the problem

we know that

tan 29°=AC/CB--------> CB=AC/tan 29°
AC=110 ft
CB--------> <span>how far the man is from the helicopter landing pad
</span>so
CB=AC/tan 29°----------> CB=110/ tan 29°----------> CB=198.45 ft

the answer is
the man is 198.45 ft from the helicopter landing pad

Answer:

37.5

Step-by-step explanation:

First you have to realize that these are similar triangles.

You can do a easy cross multiplication with these types of questions by forming an equation with the similar angles.

put the smaller above the decimal and the bigger one below like this.

$\frac{8}{25}$ = $\frac{12}{x}$

Now cross multiply

8x=300

x=37.5

•Rectangular prism - Multiply the measurement of the length times the width, then times the height

•Cube - Since all sides are the same measurement, it would be the measurement of any side, or edge, cubed, or a³

•Prism - Find the area of the base, then multiply the area times the height of the prism. Area would be length times width (B), or B x h

•Triangular prism - Find the area of the base (b), then multiply the area times the length (l) between the triangular bases. Area of the base would be ½ times the base times the height (h) of the triangle, or ½bhl

•Cylinder - Find the area of the circular face using pi times the radius squared, then multiply that area times the height of the cylinder, so πr²h

•Pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3Bh

•Square pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3s²h

•Rectangular pyramid - Find the area of the base and multiply that area times the height of the pyramid and multiply by 1/3, or 1/3 lwh

•Sphere - For a sphere, multiply 4/3 times pi, then time the radius cubed, or 4/3 πr³
