The values of x and y from the given diagram are 47 ad 86 degrees respectively
<h3>Circle theorem</h3>
From the given circle, the triangle HJL is a right triangle.
Determine the value of y
43 = 1/2 <y
<y = 43 * 2
<y = 86 degrees
Since the sum of angle on a straight line is 180 degrees, such that;
x+90+43 = 180
x + 133 = 180
x = 47 degrees
Hence the values of x and y from the given diagram are 47 ad 86 degrees respectively

<span>Hi! All you need to know is that cot stands for cotangent and its the reciprocal of tan i.e. cot(x) = 1/tan(x). You probably know that tan(pi/4) = 1 and that tan(3pi/4) = -1. Happily in these cases it means that cot and tan come out the same (1/1 = 1 and 1/-1 = -1).
-1 - (+1) = -2 and this divided by pi/2 = -2/(pi/2) which looks a bit untidy so multiply the top and bottom by 2 (to get rid of the 2 in pi/2) and the answer is -4/pi. HTH</span>
Answer:
Part a) The value of x is 10
Part b) The perimeter of triangle JKL is 
Step-by-step explanation:
Part a) Find the value of x
we know that
The <u>Triangle Proportionality Theorem,</u> states that if a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally
Part b) we know that
The perimeter of triangle JKL is equal to
substitute the values
substitute the value of x
Answer:
true
Step-by-step explanation:
the lines of the new shape are parallel to the lines of the original shape, there seems to be the same scaling factor for all sides and all "projection" lines BB' and CC' cross at A, which is also A' Ave the center of the dilation.
