Answer:
x= 27
Step-by-step explanation:
a triangle always has 180 degrees, therefore:
(3x-17)+(x+40)+(2x-5)= 180
6x+18=180
6x=162
x=162/6
x=27

Answer:
5/9
Step-by-step explanation:
The area of one triangle is ...
A = 1/2(x)(2x) = x²
Then the area of the four triangles is ...
unshaded area = 4(x²)
The length of DC is 2x+x = 3x, so the area of ABCD is ...
total area = (3x)² = 9x²
Then the fraction that is shaded is ...
(9x² -4x²)/(9x²) = 5/9
5/9 of the area of ABCD is shaded.
CPD because of the angle bisector theorem
