Answer:
x = 9.6 meters
y = 20.98 meters
Shadow length = 11.38 meters
Step-by-step explanation:
By applying tangent rule in right triangle ABD,
tan(21)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(21) = [tex]\frac{x}{25}[/tex]
x = 25(tan 21)
x = 9.5966
x ≈ 9.60 meters
Similarly, by applying tangent rule in ΔABC,
tan(40)° = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(40)° = [tex]\frac{BC}{AB}[/tex]
tan(40)° = [tex]\frac{y}{25}[/tex]
y = 25(tan 40°)
y = 20.98 meters
Length of the shadow of the man = y - x
= 20.98 - 9.60
= 11.38 meters

Answer:
6z-7>8z+2? = z < -9/2
Step-by-step explanation:
6*z-7-(8*z+2)>0
-2z - 9 = -1 • (2z + 9
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
2z+9 < 0
Divide both sides by 2
z+(9/2) < 0
Subtract 9/2 from both sides
z < -9/2
Answer: z < -9/2
Answer:
z is (less than) -9/2 is the correct answer use the symbol for less than.

Answer:
A = 250
B = 75
C = 40
Step-by-step explanation:
Apparently, we're supposed to assume that the "health gained" is proportional to the "time in circle." The constant of proportionality is 100/4 = 25. This means all the numbers in the right column are 25 times those in the left column:
A = 25·10 = 250
B = 25·3 = 75
C·25 = 1000 ⇒ C = 40 . . . . . note these numbers are 10 times those in the first row

Add all the angles in triangle 2
84 + 36 = 120
The angle that is divided between triangle 1 and 2 measures 90 degrees so we are gonna add it to the total of triangle 2
120 + 90 = 210
Because no angles in a triangle measures 210 we are gonna subtract 180 from .
210 - 180 = 30
The missing angle in the second triangle is;
180 - 120 = 60 degrees
The total we got after subtracting 180 from 210 is the missing angle for the divided side of triangle 1.
Now that we have 2 angles we can now find “?”
To find “?” we are gonna add the two angles we have and subtract it from 180.
86 + 30 = 116
180 - 116 = 64
Therefore “?” is equal to 64 degrees.

represent the cost of a pair of socks and let y represent the cost of a pair of slippers.
Identify the system of equations that represents the situation and identify the solution to the system of equation.
Answers
Answer: See explanation
Step-by-step explanation:
The information given in the question can be turned into an equation as:
2u + y = 30 ........ i
5u + y = 42 ........ ii
Subtract i from ii
3u = 12
u = 12/3 = 4
A pair of socks cost $4
Since 2u + y = 30
2(4) + y = 30
8 + y = 30
y = 30 - 8 = 22
A pair of slippers cost $22
