What is the hypotenuse of an triangle with sides 6 and 8 and angles 30 and 60 degrees?

klemol [59]

Hypotenuse ^2 = base^2 + perpendicular ^2

H^2 = 6^2 + 8^2
H^2 = 36 + 64
H^2 = 100
H = 10

(This is a right angle triangle as 60+30= 90
180-90= 90)

Which graph shows the information in the table? PLZ HELP I GIVE BRAINLIEST IM TIMED!!!!

sleet_krkn [62]

Answer:

Step-by-step explanation:

I think that's the answer because

60 minutes = 1 hr

120 minutes = 2hrs

So the graph must be constant with the write amount of min/hr since the x axis is the number of mins and the y axis is the number of hours. (x,y)

(60,1)

(120,2)

A surveyor standing on top of a cliff found that the angle of depression of a boat as sea is 22°. if the top of the cliff is 15m

Alex73 [517]

Answer:

From the photo above i interpreted the question and drew a triangle to make it easier to solve

Tan is used to solve the question as we were given opposite (as height of the cliff) and to find Adjacent ( the distance between the foot of the cliff to the boat)

Tan θ =Opp/Adj

Tan 22°=15/a

Cross Multiply

aTanθ=15°

Divide both sides by Tan 22

aTan22/Tan22 = 15/Tan 22

a = 15/Tan 22°

a = 37.13 m

Therefore the distance between the foot of the cliff to the boat is 37.13 metres
