Answer:

C 117

Step-by-step explanation:

<2 = 63

<4 = <2 vertical angles

<4 + <7 = 180

63 + <7 = 180

subtract 63 from each side

<7 = 117

It will be the same measure as angle 1

63 and angle one have to equal 180 so

180-63=117

So angle 1 is 117 and angle 7 is 117

What to write it here

Orlov [11]

Answer:

84 degrees

Step-by-step explanation:

Angle A = 83 degrees

Angle B = x degrees

Angle C = 135 degrees

Angle CDE = 122 degrees

We know that the four inner corners of a quadrilateral should add up to 360 degrees. Two supplementary angles will add up to 180 degrees. Adjacent angles on a straight line will always be supplementary. Knowing this, just solve for <ADC and add that amount to <A and <C. Then, subtract that sum from 360 degrees.

<ADC = 180-122 = 58

58+83+135 = 276

360-276 = 84 degrees

An expression involves subtracting two numbers from a positive number. Under what circumstances with the value expression be neg

Svetach [21]

So (positive integer)-x-y can be negative
so to get a negative number as your result/answer, x+y must be greater than (positve integer) so for example

lets say (positive integer)=8
x+y must be greater than 8 to make the equation negative so
example
x=5
y=4
x+y=9
8-9=-1
