Answer:
Y ≈ 59.0°
Step-by-step explanation:
Using the Cosine rule
cosY = 
with x = 22, y = 20, z = 18
cosY = 
= 
= 
, then
Y = 
( ) ≈ 59.0° ( to the nearest tenth )
Answer:
−5 < x < 10
Step-by-step explanation:
Add 1 to each part of the three parts of the inequality:
-6 +1 < x - 1 +1 < 9 +1
-5 < x < 10 . . . . . simplify
_____
The only place where there's an x is in the middle section. The only operation performed on x is subtraction of 1. To undo that subtraction, you add 1, but you must add 1 to all sides of the comparison symbols in order to keep them true.
Such a compound inequality is the same as the two inequalities:
Solving either one of these is done by adding 1 to both sides of the < symbol:
You can put these back together in the form of the compound inequality ...
-5 < x < 10
Answer:A. x squared over 16 minus y squared over 4 ...
