You can represent the measures of an angle and its complement as x° and (90 − x)°. Similarly, you can represent the measures of

an angle and its supplement as x° and (180 − x)°. Use these expressions to find the measures of the angles described. The measure of an angle increased by 50° is equal to the measure of its complement.

Answer:

11779 ft

Step-by-step explanation:

We are given that

\theta=23^{\circ}

Distance between tower and plane,d=5000 ft

We have to find the distance between the plane and bird.

Let x  be the distance between bird and plane

We know that

tan\theta=\frac{perpendicular\;side}{Base}

Using the formula

tan23=\frac{5000}{x}

x=\frac{5000}{tan23}=11779.3 \approx 11779ft

Hence, the distance between the plane and bird=11779 ft

Please help me out with this :)

Answer:

x = 1

Step-by-step explanation:

Given that y varies directly with x then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 12 when x = - 2, then

k = \frac{y}{x} = \frac{12}{-2} = - 6, thus

y = - 6x ← equation of variation

When y = - 6, then

- 6 = - 6x ( divide both sides by - 6 )

x = 1

What is greater 5/6 7/12 or 7/10
algol [13]
5/6
you can do 2 things here
use a calculator and divide the numerator by the denominator
or the method you're probably meant to use
change each fraction so they all have the same denominator
the common denominator in this case would be 60
5/6*10=50/60
7/12*5=35/60
7/10*6=42/60
the number with the highest numerator would be the larger fraction
in this case, being 50/60 or 5/6
