Ms. Alonzo received 400 markers because one tenth of 4000 is 400. Hope this helped!
Answer:
x = 71
Step-by-step explanation:
Since 2 sides of the triangle are congruent then the triangle is isosceles.
Thus the 2 base angles are congruent
The sum of the 3 angles in the triangle = 180°, so
x =
=
= 71
-3xa=-3a
-3x6=-18
so it is (i think) -3a+-18
I do not know the answer I just need points so I can ask another question sorry
1: 2/7 (I think)
2: √2 −3
——
3
(Number 2 is probably difficult but the two lines underneath is where the number is supposed to be)
3: 4√10
