Angle a= 7x + 40°
angle b= 3x + 112°
solve for x then find the meansie if angle a.
angle a =

a = 166°

Step-by-step explanation:

7x + 40 = 3x + 112

x = 18

a = 7(18) + 40 = 166

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
