The values of x are x = -0.77 and x = 3.27
<h3>How to determine the value of x?</h3>
To calculate the value of x. we start by using the following equivalent ratio
2x : (3.5 + x + 1.5) = x + 0.5 : x + 1.5
Evaluate the like terms
2x : (5 + x) = x + 0.5 : x + 1.5
Express the ratio as a fraction
2x/5 + x = x + 0.5/x + 1.5
Cross multiply
2x(x + 1.5) = (5 + x)(x + 0.5)
Open the brackets
2x^2 + 3x = 5x + 2.5 + x^2 + 0.5x
Evaluate the like terms
x^2 - 2.5x - 2.5 = 0
Using a graphing calculator, we have
x = -0.77 and x = 3.27
Hence, the values of x are x = -0.77 and x = 3.27

So hmmm notice the picture below
get the area of the "square" that contains both triangles
and then subtract the area of that gray triangle
notice the base of the triangle, is just 14, the height is 14
the difference, is the area other two blue smaller triangles

9514 1404 393
Answer:
(c) 31°
Step-by-step explanation:
Angles 1 and 2 are congruent. Each is half the sum of the subtended arcs:
∠1 = ∠2 = (37° +25°)/2 = 31°
