1. Find x and then the value of all 4 angles (A, B, C) 2. Find the values of angles 1,2,3 (A, B, C)
3. Solve for x (A, B, C)
4. Solve for x (A, B, C)

BTW you don't have to show how you did the work, I only need the answers​

37/3

step-by-step explanation:

step 1: simplify both sides of the equation.

7x+8(x+

1

4

)=3(6x−9)−8

7x+(8)(x)+(8)(

1

4

)=(3)(6x)+(3)(−9)+−8(distribute)

7x+8x+2=18x+−27+−8

(7x+8x)+(2)=(18x)+(−27+−8)(combine like terms)

15x+2=18x+−35

15x+2=18x−35

tep 2: subtract 18x from both sides.

15x+2−18x=18x−35−18x

−3x+2=−35

step 3: subtract 2 from both sides.

−3x+2−2=−35−2

−3x=−37

step 4: divide both sides by -3.

−3x

−3

step-by-step explanation:

care to share were the trapezoid shown is ?

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
