Step-by-step explanation:
its just moving the point.
3.72 x 10^6 you moved the point 6 times to the left so its positive.
5 x 10^-11 moved it 11 times to the right so its negative
Answer:
D. 0.65
Step-by-step explanation:
divide 52 by 80.
52/80 = 0.65
Answer:
Angle D is equal to 80.
Step-by-step explanation:
We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.
Triangles' angles always add up to 180.
180 - 70 - 30 = 80
angle D is equal to 80.
Answer:
d. 40
Step-by-step explanation:
2x + x +( x + 20) have to all equal 180 degrees in a triangle.
2x + x + x + 20 = 180
2x + 2x + 20 = 180
4x + 20 = 180
4x = 180 - 20
x = (180-20) / 4
x = 160 / 4
x = 40
