Answer:
From given relation the value of β is 37.5°
Step-by-step explanation:
Given as :
α and β are two acute angles of right triangle
Acute angle have measure less than 90°
Now given as :
= 
Or, 
=
SO, 
= 
Or, 90° = + 
or, 90° = 
+ 4x
Or, 90° = 
So, x = 
= 15°
∴ = 
So, = sin
∴ The value of Ф_1 = = 37.5°
Similarly = 
So ,The value of Ф_2 = 
= 52.5°
∵ β 
α
So, As 37.5°52.5°
∴ β = 37.5°
Hence From given relation the value of β is 37.5° Answer
Answer:
s = 17 units
Step-by-step explanation:
The Pythagorean theorem applies:
8^2 + 15^2 = s^2
64 + 225 = s^2
289 = s^2
√289 = 17 = s
The value of s is 17 units.
A+b = 5
b+c= 3 1/2
2 times 2 + 3 = 7
a times d =8
c+c = 1
(e)2 = 1/9

Answer:
There are no enough information to determine the length of the fence, assuming we were given the perimeter of the fence, and say, the dimension of the fence, then we can easily find the length.
Perimeter of the fence, P = 2(L + B).. If the fence is a rectangular.
L = (P/2) - B
If the fence is square, P = 4L
L = P/4
