Answer:
B - 6sqrt(23) ft.
Step-by-step explanation:
Area = (Side)^2 = 828.
Side = sqrt(828) = sqrt(36*23) = 6 sqrt(23).
So B - 6sqrt(23) ft.
Mark me as Brainliest if this is correct! I really appreciate it! :D
Answer:
x = 10 units
Explanation:
First, let's consider the smaller triangle.:
It is a right-angled triangle, therefore, we can use the special trig functions.
tan θ = opposite / adjacent
tan 45 = opposite / 5
opposite = 5
Now, for the larger triangle:
It is also a right angled triangle which means that we can use the special trig functions.
sin θ = opposite / hypotenuse
sin (30) = 5 / x
x = 10 units
Hope this helps :)
Answer: Part A. The value of x= 20 . Part B the value of y=35
Step-by-step explanation:
5x + 4x = 180 because both of them lies on a straight line
9x=180
x=20
2y = 70
y= 35
Answer: 32 degrees
Step by step:
3 angles in a triangle add up = 180 degrees
180 - 76 - 72 = 32
so x = 32
Hope this helps :)
