Answer:
60
Step-by-step explanation:
In this case, all of the sides are equal. All sides should add up to 180 degrees.
x+x+x=180
180/3= 60
Answer:
5
+40
Step-by-step explanation:
perimeter of circle=2
r
so 5 is r(radius)
so 10
, but since it’s semicircle, you have to divide by 2, so
5
perimeter of rectangle=15+10+15 because you don’t count the inside, so that equals 40
so 5
+40
Answer:
x < 7
Step-by-step explanation:
First apply the -2 onto each term that it is being multiplied onto.
-2x + 6 > - 8
Now subtract six from both sides.
-2x > -14
Now divide by -2.
x < 7
<u>REMEMBER</u>
When doing greater than and less than equations like this, if you divide by a negative you must flip the greater than/less than.
