Difference would be that is a diameter is double a radius and a radius is half of a diameter.
A similarity would be that they would are within a circle and touch the center of circle
Answer:
6) f=45
7) r=57
Step-by-step explanation:
the angles of a triangle will always add up to 180 degrees. Therefore, for the first one the three inside angles have to be 30, 15, and 135. If 135 is the supplementary angle to f, 45 must be the degree of f.
Same idea for the second one. 180-143=37. so 37+86+r=180. solve for r to get 57.

Here we have the following expression:

We combine like terms in order to simplify expression. To do so, we combine terms with the same variable and exponents. In this exercise, let's apply distributive property first:

Answer:
y=7.5
Step-by-step explanation:
25y -15y =75
10y=75
y=7.5

Given is an A.P. in which -
- First term,a = 2
- Common difference = Second term - First term



<h3><u>Solution:- </u></h3>
nth term of an A.P ,is given by-

where

- a = first term
- n = number of term
- d = common difference
Putting n = 46




Therefore, the 46th term is 227
