Answer:
x = 12
Step-by-step explanation:
The given triangle is isosceles, so the two remaining angles in the triangle both have measure <em>xº</em>. The interior angles of any triangle sum to 180º, so that
58º + <em>xº</em> + <em>xº</em> = 180º
58 + 2<em>x</em> = 180
2<em>x</em> = 122
<em>x</em> = 61
Angles <em>y</em> and <em>z</em> are supplementary to angle <em>x</em>, so that
<em>xº</em> + <em>yº</em> = 180º
and
<em>xº</em> + <em>zº</em> = 180º
and consequently, <em>y</em> = <em>z</em>. In particular, we get
<em>y</em> = 180 - 61
<em>y</em> = 119
and so
<em>z</em> = 119
Answer:
-1 < c < 9
Step-by-step explanation:
-6<2c-4<14
Add 4 to all sides
-6+4<2c-4+4<14+4
-2<2c<18
Divide by 2
-2/2<2c/2<18/2
-1 < c < 9

Answer:
1 hour and 42.8 minutes
Step-by-step explanation:
To answer this question let's call 
while it takes Jenna to clean the gutters
Let's call 
while it takes John to clean the gutters
h
h
t = total time
g = job = 1 (clean the gutters)
The speed of each one is:
g/ h
g/h
So:
h
Then, both together paint 
of gutters for each hour.
This means that it takes 
hours to clean the gutters together
Finally cleaning together takes 1,714 hours or also
1 hour and 42.8 minutes
