Answer:
the value of the expression is 10
Step-by-step explanation:
The expression means the product of 5 and the difference of three times r minus 10.
'r' represents the variable
three times 'r' is 3r
for minus 10, subtract 10 from 3r
the product of 5 and the difference of three times r minus 10.
Now evaluate the expression when r=4
Plug in 4 for 'r' in the expression we got
10

When you have two parallel lines being cut by a transversal, you can use the next statements for the angles:
The measurement of the angles in green is the same (are congruents)
The measurement of the angles in blue is the same (are congruents)
An angle in green is a complementary angle with an angle in blue. (The addition of the two angles has to be 180º)
You know that:
As the angle 3 is congruent with angle 2:
