Step-by-step explanation:
a) The measure of angle 7 is also 47 degrees. We know this because angle 5 and angle 7 are vertical angles and vertical angles are always equal.
b and c) Since we know that a straight line has an angle of 180 degrees and that the sum of angle 5 and angle 6 will add to this, we can use that to find the value of x like this:
Answer:
$9.35
Step-by-step explanation:
14.86+25.88+5.76=46.5
55.85-46.5=9.35
Answer:
40 or 45%
Step-by-step explanation:
Answer:
Choice A.......< B is 147 degrees
Step-by-step explanation:
The total sum of the interior angles of a pentagon is 540 degrees
...So let's count the angles that we already have:
<A is 90
<B is ?
<C is 105
<D is 108
<E is 90
Noticed that both angles A and E are 90 since they have that little square that represents a straight angle.
Let's find the value for <B
90+ x + 105 + 108 + 90= 540
393 + x= 540
x= 540 -393
x = 147
So angle B is 147 degrees
