Air traffic controller Seymour Plains must quickly calculate the altitude of an incoming jet. He records the jet’s angle of elevation as 8°. The jet signals that its land (horizontal) distance from the control tower is 74 km. Calculate the altitude of the jet to the nearest meter

Altitude of the jet is 10.40km

Step-by-step explanation:

The angle of elevation = 8°

Horizontal distance (adjacent to the angle) = 74km

Altitude of the plane (opposite) = ?

Kindly check attached document for better illustration.

To solve this question, we have to use tangent rule since we have adjacent and angle, but no opposite.

Tanθ = opposite / adjacent

θ = 8°

Adjacent = 74km

Opposite = ?

Tan 8 = x / 74

Opposite = 74 * tan8

Opposite = 10.40

The altitude of the jet is 10.40km

#15. square

step-by-step explanation:

because quadrilatural (idk how to spell it) means somthing that is not 3d or like, equal sides (or somthing like that   you know what i meanz)

hope this halps!

bai!

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
