Answer:
Step-by-step explanation:
Given
Options (a) to (d)
Required
Which represents an arrow pointing left
When an arrow points left on an inequality graph, the inequality is either of the following:
or 
From the given options (a) to (d), only fits the above description.
Other options illustrate an arrow pointing to the right
To further explain this;
Looking at (b), we have:
This is rewritten as:
--- the same form as (c) and (d)
Answer:
Step-by-step explanation:
Using the inequality rule, the third side has to be less than 12 + 16 = 28.
So, any answer of 28 or more than 28 does NOT satisfy the length.
It also has to be more than 4 to satisfy the inequality rule.
In short words, 4 < x < 28.
A, B and C all satisfy, because they are in the range of x
D) 32 is >28, so this is the wrong answer and CANNOT be the value of x.
Answer:
70°
Step-by-step explanation:
Since PTS shape is equal to QTR
and PTQ shape is equal to STR
and Since QTP = 10
and Since PTS = 60
Add both up 70
Therefore PQR = 70°
36/2=18.
The answer is 18.
