Answer:
I think it's 4. reflection and glide refection.
Step-by-step explanation:

We can write it az 2 minus sum of p and 6
As p and 6 are in bracket therefore first we add p and 6 and then subtract the sum from 2
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
