Answer:
74 degrees
Step-by-step explanation:
You can see this is a supplementary angle, which means that it is a straight line with a line sticking out. This means the two angles add up to 180 degrees, so 180 - 106 = 74, which is your answer.
Answer:
√55
Step-by-step explanation:
Notice that the small triangle in the bottom corner shares an angle with the overall triangle. Also, they are both right triangles. Therefore, they are similar triangles.
Notice that the large triangle at the top shares an angle with the overall triangle and is also a right triangle. Therefore it is also similar to the overall triangle and the smaller triangle.
Writing a proportion between the small and large triangles:
y / 11 = 5 / y
y² = 55
y = √55
Width = 5.5yd
Length = 12yd
<u>Explanation:</u>
Area of rectangle = 
Let width of the rectangle = b ,
So, length = 2b+1
Area of rectangle = (length X width) - eqn 1
Putting the value of length and width in above equation 1,

On solving the equation we get,
b = 5.5yd
So, width (b) = 5.5yd
and length = 2(5.5) + 1
l = 12yd
Hence,
Width = 5.5yd
Length = 12yd
