Answer:
x=66
Step-by-step explanation:
Every triangle is equal to 180 degree angles so if you do 83+31, then that is equal to 114, which is when you do 180-114 and that would be 66. So your answer would be x=66
Answer:
87.96yd
Step-by-step explanation:
C=2πr=2·π·14≈87.96459yd
It’s A. Since every aspect of that is multiplication, you can change around how you write it such as (6*7)^3. 6*7 is 42, and 42^3 is the exact same as 42^3

Step-by-step explanation:
Answer:
B
Step-by-step explanation:
In the right triangle with hypotenuse of 10 use the sine ratio to find x
sin20° =
= 
Multiply both sides by 10
10 × sin20° = x, hence
x ≈ 3.4 ( to the nearest tenth ) → B
