Answer:
7,2,3
Step-by-step explanation:
Congruent angles means that both angles have same measure.
Remember that if both lines cross-intersect each others, both form same measure.
Therefore:-
angle 6 = angle 7
Assume that both lines are parallel, we can say that angle 6 = angle 2
Since angle 6 = angle 2 and angle 2 = angle 3 via cross-intersect, that means angle 6 = angle 3 as well. angle 6 = angle 3 is alternate interior angle theorem.
Thus:- angle 7, 2 and 3 both are congruent
Answer:
y≥14
Step-by-step explanation:
Add 27 to both side so
y-27+27≥-13+27
so
y≥14
It is 36,39,42,46,51,53. You start by crossing out the ends. You are left with 42 and 46. Add those and divide by 2. That is the answer.
Answer:
a = 1
Step-by-step explanation:
Since x = - 1 is a zero of p(x) then p(- 1) = 0
Substitute x = - 1 into p(x)
p(- 1) = a(- 1)² - 3(a - 1)(- 1) - 1 = 0, that is
a + 3(a - 1) - 1 = 0
a + 3a - 3 - 1 = 0
4a - 4 = 0 ( add 4 to both sides )
4a = 4 ( divide both sides by 4 )
a = 1
