Geometry Values of a Kite
Evgen [1.6K]

Answer:

x=7

y=18

The length of each of the two shorter sides is 14.

The length of each of the two longer sides is 19.

Step-by-step explanation:

2x+5 = x+12 and y-4 = x+5

Solve for x first

2x+5-5 = x+12-5 Subtract 5 from both sides to eliminate it.

2x-x = x-x+7 Subtract x from both sides to eliminate it.

x=7 Now, substitute 7 for x in y-4 = x+5 to solve for y.

y-4 = (7)+5

y-4 = 12

y-4+4 = 12+4 Add 4 to both sides to eliminate it.

y = 18

Finally, we can substitute 7 for x and 18 for y in all equations to see the lengths of each side.

(18)-4=14 The length of each of the two shorter sides is 14.

2(7)+5=19 The length of each of the two longer sides is 19.

A boy walks 58 feet up a ramp having a 22.5 degree inclination. how high is he standing from the ground?
yKpoI14uk [10]

Boy is 22.5 feet high from the ground

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

The given question can be solved by sin, as value of perpendicular is to be evaluated and height and angle is provided. Let height from the ground be x

sin(22.5°) = x / 58

x = 58sin22.5 = 58(.38258)  =  22.5 feet high.

Thus the Boy is 22.5 feet high from the ground.
