the theory is ab=cd where the lines across form eachother are a and b and the other two lines are a and d

a=7

b=n+4

c=5

d=n+8

7(n+4)=5(n+8)

7n+28=5n+40

2n+28=40

2n=12

n=6

Please help with this ☝️
kipiarov [429]
The two angles (6x+4) and 32 degrees are complementary angles. They add to 90 degrees. The two angles are adjacent and form a right angle. The right angle marker is the square marker. Two adjacent right angles form a straight angle (180 degrees)

Add up the angles and set the sum equal to 90. Then solve for x
(6x+4) + (32) = 90
6x+4 + 32 = 90
6x+36 = 90
6x+36-36 = 90-36 .... subtract 36 from both sides
6x = 54
6x/6 = 54/6 ... divide both sides by 6
x = 9

Since x = 9, this means that
6x+4 = 6*9+4 = 54+4 = 58

So the missing angle is 58 degrees (note how 58+32 = 90)
