Step-by-step explanation:
The angles in the first pair are congruent and 40° each (XYZ and XYW are complementary)
Segment FG is 4 cm while segment DE is 6 cm so they are not congruent
As shown on the figure both segment OR and segment OS is 2 in. long
Angle 2 and angle 4 are congruent
Angle ROQ and angle ROP are congruent because all angles shown on the figure has a measure of 90°
Answer:
C
Step-by-step explanation:
According to formula
(a+b)(a-b)=a²-b²
So
(y+9)(y-9)
=y²-(9)²
=y²-81

Answer:
False
Step-by-step explanation:
The total number of sections is 12
3 blue sections, 5 red sections and 4 green sections
P(red) = 3 red/ 12 total = 1/4
Spin 24 times
24 * P (red) = 24*1/4 = 6
We would expect 6 red spins
