A handicap ramp that is 25 feet long coves a ground distance of 22 feet. To the nearest degree, what is the angle of elevation o

bazaltina [42]

Answer:

28.36°

Step-by-step explanation:

The problem represents a right angled triangle as shown in the diagram below.

The length of the handicap ramp is 25 feet.

The side ground distance covered by the ramp is the adjacent of the angle of the triangle and it is 22 feet.

To find the angle of elevation of the incline, we apply SOHCAHTOA:

cos θ = adj / hyp

Therefore:

$cos \alpha = 22 / 25\\\\cos \alpha = 0.88\\\\\alpha = cos^{-1} 0.88\\\\\alpha = 28.36^o$

The angle of elevation of the incline for the handicap ramp is 28.36°.

Polygon stuv is reflected over the x axis and then over the y axis to create wxyz . Which of the following sides are congruent ?

JulsSmile [24]

Answer:

ST and WX are congruent ⇒ first answer

Step-by-step explanation:

∵ S = (-5 , -4) , T = (-3 , -1) , U = (-1 , -3) , V = (-2 , -6)

∵ STUV reflected over the x-axis

∴ S' = (-5 , 4) , T' = (-3 , 1) , U' = (-1 , 3) , V' = (-2 , 6)

∵ S'T'U'V' reflected over the y-axis

∴ S" = (5 , 4) , T" = (3 , 1) , U" = (1 , 3) , V" = (2 , 6)

∵ W = (5 , 4) , X = (3 , 1) , Y = (1 , 3) , Z = (2 , 6)

∴ S"T"U"V" is WXYZ

∴ ST and WX are congruent
