Answer:
B
Step-by-step explanation:
rotate 180 --> translate up by 4: (x,y)--> (-x,-y) --> (-x,-y +4)
<u>Given</u>:
Let A denote the angle of the given triangle which measures ∠A = 81°
Let B denote the angle which measures ∠B = 40°
The length of the side a = x.
The length of the side b = 7 cm.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the law of sine formula.
Applying the law of sine, we have;

Substituting the values, we have;

Simplifying, we get;

Cross multiplying, we have;



Thus, the length of the side x is 10.8 cm.
Answer:

Step-by-step explanation:

The statement is false for any value of x because both sides are identical after distributing and collecting like terms -10x-5>-5-10x making it equal and not bigger
Say, width = x
length = 2x +5
(x+2x+5)*2= 6x+10
6x+10=106
x= 96/6=16
Width =16 Mt
Length =37 mt
