The equation
(y + 5) + y = 6
shows the substitution method being used to solve the system of linear equations. So the correct option among all the options given in the question is option "D".
For a better explanation, let us first write down the two equations given in the question.
x + 5 = 6
and
x = y + 5
Now the thing that has been done is that the value of x in the first equation has been replaced by the value of x that is given in the second equation. this is actually the substitution method of solving equations.
This is easy all you do to find the surface area is to multiply base the number that is across by the height the number that shows the height.The you just multiply those 2 and you got the surface area.For number one the answer is,20.For two the answer is, 6.Need more help ask me under in the comments. If this was helpful please give me brainiest answer. Hope this Helps :D
Answer:
angle 2 is 43 as the opposite side of the angle is always equal angle 1 and 3 are:
step 1
43+43=86
step 2
360-86=274
step 3
274÷4=68.5
we subtracted 86 with 360 because 360 is the sum of all the angles we then divided the answer by 2 as we were suppose to find two angles angle 1 and 3 are opposite angles so they both will be same
hope this information helps u :)
