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)° = 
tan(21) = 
x = 25(tan 21)
x = 9.5966
x ≈ 9.60 meters
Similarly, by applying tangent rule in ΔABC,
tan(40)° = 
tan(40)° = 
tan(40)° = 
y = 25(tan 40°)
y = 20.98 meters
Length of the shadow of the man = y - x
= 20.98 - 9.60
= 11.38 meters
To find the hypotenuse of a right triangle, use the following formula:

Your a and your b are your legs. Plug them in. In this case, we plug in 7 for both.



Your answer would be:
Approximate: 9.9
Exact: 
First solve the first equation to find x.
x-5=2
x=7
Now plug it in to the other equation to get your answer.
6(7)-20
42-20
22
The answer is 22.

Answer:
a) ∠DAE = 33°; ∠ABD = 57°
b) ∠CEB = 90°
c) ∠ABE = 22°
d) ∠ADE = 15°
Step-by-step explanation:
The diagonals of a rhombus meet at right angles. Each bisects the corner angles at its ends. Adjacent angles are supplementary, opposite angles are congruent, and each diagonal creates two isosceles triangles.
a) ∠DAE = 90° - ∠ADE = 90° -57°
∠DAE = 33°
∠ADE = ∠ABD = 57°
__
b) ∠CEB = 90° . . . . . the diagonals meet at right angles
__
c) ∠ABE = 44°/2
∠ABE = 22°
__
d) ∠ADE = 90° -(1/2)∠DAB = 90° -150°/2
∠ADE = 15°
Answer:
you need to see which one is the most and order them by small to big I hope it helps and I learned this once so this all I have! good hopes to all
Step-by-step explanation:
order them by small to big to have the biggest one and I am a middle schooler so I hope this works!
