The answer is all real numbers for x
because simplifying, you get both sides are equal
11) First, add 74 and 43.
74+43=117
Subtract 117 from 180. Do this because this will give you the value of angle 1. This is because the sum of the angles in a triangle will always add up to 180 degrees.
180-117=63
Angle 1 = 63 degrees
Angle 2 also equals 63 degrees, because they are vertical angles.
Angle 2= 63 degrees
Now, add 63 and 79
63+79=142
Subtract 142 from 180
180-142=38
Angle 3 = 38 degrees
12)
First, subtract 56 from 180. Do this to find angle C. They are supplementary angles, so they will equal 180 degrees.
180-56=124
Angle C=124 degrees
Now, add 124 and 20
124+20=144
Finally, subtract 144 from 180
180-144=36
The measure of angle A is 36 degrees
Hope this helped! :)
Answer:
the first blank is 100
the second is 80
Step-by-step explanation:
Answer:
9x squared + 12x
Step-by-step explanation:
The answer is c. 
a. 
(2.2≠5.11) (2.2 is not equal to 5.11)
b. 
or 0.625 (0.625≠5.11) (0.625 is not equal to 5.11)
c. 
(5.11=5.11) (5.11 is equal to 5.11)
Therefore c is the answer
