Answer:
x = 20
Step-by-step explanation:
m<ABC and m<CBA are complementary angles which means their sum is 90 degrees:
2x + 3x - 10 = 90 add like terms
5x - 10 = 90 add 10 to both sides
5x = 100 divide both sides by 5
x = 20 to find the angles replace x with 20
m<ABC = 40 and
m<CBA = 50
I think it’s even because it can be divided by 2
Answer:
The value of x is 11.
Step-by-step explanation:
Consider the provided information.
It is given that 
We know that:

Now if we divide the number 81 with 32 it will gives us remainder 17.
This can be written as:

Now use the property: 

17²=289, if we divide 289 with 32 it will gives us remainder 1, thus.

Multiply both the sides by 3³.


Hence, the value of x is 11.
