Answer:
x = 24
Step-by-step explanation:
The formula for determining the sum of interior angles is:
Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.
The equation and answer above shows how to find x, which equals 24.

Answer:
135
Step-by-step explanation:
all triangles have angles that add to 180. angle a is 28 angle c is 17 which makes angle BAC 135
Answer:
logₓ(y) =
or
= 1
Step-by-step explanation:
Data provided:
a ≠ 1 and b ≠ 1
To prove
RHS = 1
LHS =
Now,
We have the property of the log function as:
logₓ(y) =
applying the above property on the LHS side to solve LHS, we get
LHS =
or
LHS = 1
Since,
LHS = 1 is equal to the RHS = 1
Hence, proved that
