Answer:
The value of x is 9°
Step-by-step explanation:
The given parameters are;
ΔUVW with side UW extended to X
m∠UVW = (3x + 4)°
m∠VWX = (8x -12)°
m∠WUV = (x + 20)°
We have that m∠UVW + m∠WUV + m∠VWU = 180° (Sum of the interior angles of a triangle theorem)
∴ m∠VWU = 180° - (m∠UVW + m∠WUV)
Also we have that m∠VWX and m∠VWU are supplementary angles, (The sum of angles on a straight line)
∴ m∠VWX + m∠VWU = 180° (Definition of supplementary angles)
m∠VWU = 180° - m∠VWX
∴ m∠VWX = (m∠UVW + m∠WUV)
Substituting the values, gives;
(8x -12)° = (3x + 4)° + (x + 20)°
8x - 3x - x = 4 + 20 + 12
4x = 36
x = 36/4 = 9
x = 9°.
Im not 100% sure but
1.square root of 0.4

The answer is 3/10 ( hope this helps)
We know that a soccer field is in the shape of a rectangle; and we know that the area is equal to length times width (A = l*w).
We are given the area as 7,700 sq. yds. and the width as 70 yds., so we can plug those into the equation to find the length (l):
A = l*w
7,700 = l*(70)
l = 100 yds.
With the length known, we can then determine the perimeter, which, for a rectangle, is:
P = 2l + 2w
So we can then plug in the values for the length and the width:
P = 2(110) + 2(70)
P = 220 + 140
P = 360 yds
The perimeter of the soccer field, which we now know, is 360 yds.
