Answer:
The base is 19.5.
Step-by-step explanation:
The given question is, "The perimeter of a rectangle is 58 and its base exceeds its width by 10, how long is the base?"
Perimeter = 58
Base, l = 10+b
The perimeter of a rectangle is :
P = 2(l+b)
58 = 2(10+b+b)
29 = (10+2b)
29-10 = 2b
19 = 2b
b = 9.5
Base, l = 10 + 9.5
= 19.5
Hence, the base is 19.5.

Answer: B. 781.6 feet approximately</h3>
=======================================================
Work Shown:
The horizontal portion is 400+166 = 566 feet. Label this as 'a', so a = 566. The vertical side is unknown, so b = x. The hypotenuse is c = 965
Use the pythagorean theorem
a^2+b^2 = c^2
566^2+x^2 = 965^2
x^2 = 965^2 - 566^2
x = sqrt( 965^2 - 566^2 )
x = 781.58108984289 which is approximate
x = 781.6 feet when rounding to one decimal place
It’s 4/15
Answer = 3 3/4

Answer:
Step-by-step explanation:
Answer: Angle of elevation of sun at that time is 24.51° .
Step-by-step explanation:
Since we have given that
Height of a large totem pole near Kalama, Washington = 100 feet
Length of a shadow at noon = 219 foot
We need to find the angle of elevation of sun at that time .
As we know the formula for "Tangent ":
Hence, Angle of elevation of sun at that time is 24.51° .
