The complete question in the attached figure
we know that
tan R°=opposite side angle R/adjacent side angle R
opposite side angle R=72 units
adjacent side angle R=25 units
so
tan R°=72/25
R=arc tan (72/25)---------> R=70.85°-------> R=70.9°
the answer is R=70.9°
Answer:
D
Step-by-step explanation:
Tenth vs Hundreth.... ten times larger
C because they all have to add up to 180 and 20+130=150 and 180-150=30
Let's analyze the increments for each step of the sequence:
Each step we add 3 to the previous number.
Since we need the 20th, from what we saw, in the 20th term we will have added three 20 times.
So the procedure is: calculate how much is 3 times 20 and then add that to the first term of the sequence.

So we add 60 to the first term to find the 20th term:

Answer: 124
