Answer:
25
Step-by-step explanation:
I added them
That's going to depend completely on the unit of
the 4.5 which, sadly, you have not mentioned.
You are multiplying by 3 each time. This sequence is geometric.
9 = 3*3 = 3^2
27 = 3*9 = 3*3*3 = 3^3
81 = 3*27 = 3*3*3*3 = 3^4
and so on.
The general rule is 3^x which is choice D

Answer:
168). C
169). C
170). C
Step-by-step explanation:
For the first angle, it is a right angle, so it measures 90 degrees.
x and 50 are complementary angles, meaning they add up to 90 degrees.
So, subtract 50 from 90 to get 40, which is equal to x.
45 and x are supplementary angles, meaning they add up to 180 degrees.
Subtract 45 from 180 to get 35 degrees, which is the measure of angle x.
All angles in a triangle add up to 180 degrees.
So, 70 + 56 = 126, 180 - 126 = 54.
Since the unknown angle is x - 5, 54 + 5 = 59, which the the measure of angle x - 5.
