Answer:
AC = 30 units
Step-by-step explanation:
if AB = BC, then this is an isosceles triangle.
further BX intersects the base (AC) of the isosceles triangle at a right angle.
This means that the line of symmetry BX divides triangle ABC into two congruent triangles where AX = CX.
hence AC is
AX + CX
= CX + CX
= 15 + 15
= 30 units

Answer:
-2
Step-by-step explanation:
x + 3 = 2x + 5
-2 = x
Answer:
15
Step-by-step explanation:
20^2 + x^2 = 25^2
= 400 + x^2 = 625
= x^2 = 225
= x = 15
Answer:
B. -6
Step-by-step explanation:
The common difference here is the difference between each term. Since it is an arithmetic sequence the difference between each term will be the same value.
So, from 45 (the 1st term) to 39 (the 2nd term), the difference is -6
From 39(the 2nd term) to 33, the difference is also -6.
Therefore, we know that the common difference fro this arithmetic sequence is -6.
Hope this helps and ask me any question if it does not :)
