Answer:

x = 2.5

Step-by-step explanation:

12x - 13 = 17

12x = 17 + 13

12x = 30 (divide both sides by 12 to get x)

12x/12 = 30/12

x = 2.5

Malaya is standing directly between a 90-foot tall courthouse and a 54-foot tall bank. If the angle of elevation from the point
Alex

Answer:

Step-by-step explanation:

Draw a picture.

c and b are Malaya’s distance from the courthouse and bank, respectively.

tan(72°) = c/90

c = 90tan(72°)

tan(35°) = b/54

b = 54tan(35°)

Distance between courthouse and bank = c+b

= 90tan(72°) + 54tan(35°)

= 301.5 ft

Which two lines are parallel?<br> Which two lines are perpendicular?
lana66690 [7]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

All the equations given are in slope- intercept form

y = 2x + 1 → with m = 2

y = \frac{1}{2} x - 4 → with m = \frac{1}{2}

y = x + 1 → with m = 1

y = - \frac{1}{x} x - 3 → with m = - \frac{1}{2}

y = 10 + x → y = x + 10 → with m = 1

Thus

y = x + 1 and y = 10 + x are Parallel since both have m = 1

y = 2x + 1 and y = - \frac{1}{2} x - 3 are Perpendicular since 2 × - \frac{1}{2} = - 1

What is the measure of the missing angle in the triangle below?
nirvana33 [79]

Answer:

<em>41 degrees</em>

Step-by-step explanation:

<em>According to Angle Sum Property, the sum of the internal angles of a triangle is equal to 180 degrees.</em>

<em>Therefore,</em>

<em>52 + 87 + ? = 180</em>

<em>139 + ? = 180</em>

<em>? = 180 - 139</em>

<em>? = 41 degrees</em>
