If a line has a slope of 3, what is the slope of a perpendicular line?

pashok25 [27]

Answer:

Slope of perpendicular line is -1/3

Step-by-step explanation:

The slope of the given line is 3 and we have to find the slope of the perpendicular line.

We know that the slope of two perpendicular lines are negative reciprocal of each other.

In other words if the slope of the line is m then then slope of the perpendicular line is $-\frac{1}{m}$

The reciprocal of 3 is $\frac{1}{3}$

Hence, negative reciprocal of 3 is $-\frac{1}{3}$

Therefore, the slope of perpendicular line is -1/3

C is the correct option.

A building casts a 32m shadow when the sun is at an angle of 30 degrees to the vertical. How tall is the building to the nearest

sdas [7]

Answer:

16m tall

Step-by-step explanation:

Distance casted by the shadow = 32m = hypotenuse

Angle of elevation = 30 degrees

Required

Height of the building = opposite

Using the SOH CAH TOA identity

sin theta = opp/hyp

sin 30 = x/32

0.5 = x/32

x = 0.5 * 32

x = 16m

Hence the building is 16m tall

What is the sin, cos, and tan of -495 degrees, and -20π/3 ??

Diano4ka-milaya [45]

Sin-495 = 0.98
cos-495 = 0.19
tan-495 = 4.95

sin-20π/3 = 0
cos-20π/3 = 0.3
tan-20π/3 = 0
