Answer:
D
Step-by-step explanation:
they all should equal 180
d does not
We can use pythagorean theorem to find the side of one of the triangles/
12^2 + x^2 = 15^2
x = 13
Since there are two of these triangles:
x = 13+13
x = 26
Hope this helps!
One sixth of a right angle (90 degrees) would be 15 degrees.
C, move the decimal point to the left according to the exponent on the 10, in this case 4 steps.
