Answer: Correct Answer is 4th option , 28
Step-by-step explanation:
We can find the measure of the angle using the tangent.
We know, tangent of an angle = Perpendicular/Base, corresponding to that angle.
So, Tan of angle T = RG / RT
or, Tan of angle T = 8/15
or, angle T = tan inverese of 8/15
or, angle T = 28.07
So, angle T rounded to nearest degree = 28
Hope this helps.
Thank you.
We know that
mGJI+117.33°=360° (full circle)
so
mGJI=360°-117.33°-----> 242.67°
the answer is
242.67°
Answer:
9 5/12
Step-by-step explanation:
2 2/3 + 6 3/4
find a common denomenator. For 3 and 4, it would be 12.
2 8/12 + 6 9/12
add
8 17/12
12 goes into 17 one time, with 5 left over
9 5/12
Answer:
Step-by-step explanation:
The the area of the rectangular pen be A = LW
L is the length
W is the width
Given
A = 3136ft²
3136 = LW..........1
Given the perimeter P = 2L+2W....... 2
From 1; L = 3136/W
Substitute into 2
P = 2(3136/W)+2W
P = 6272/W + 2W
In order to minimize the amount of material needed, then dP/dW = 0
dP/dW = -6272/W² + 2
0 = -6272/W² + 2
6272/W² = 2
cross multiply
6272 = 2W²
W² = 3136
W = √3136
W = 56ft
Since A = LW
3136 = 56L
L = 3136/56
L = 56ft
Hence the dimensions of the rectangular pen that minimize the amount of material needed is 56ft by 56ft
