Answer:
c = -3
Step-by-step explanation:
Call the unknown c
c(x-3) +2x = -(x-5) +4
Distribute the negative sign
c(x-3) +2x = -x+5+4
Combine like terms
c(x-3) +2x = -x +9
Subtract 2x from each side
c(x-3) +2x-2x = -x-2x +9
c(x-3) = -3x+9
Factor a -3 from the right side
c(x-3) = -3(x-3)
Divide by (x-3)
c = -3
The right and left hand side need to be equal for there to be infinite solutions, so c = -3
Answer:
229°
Step-by-step explanation:
51 + 51 = 102
360 - 102 = 458
458 / 2 = 229
Step-by-step explanation:
step 1. AD is parallel to BC
step 2. <y = 90° (definition of right trapezoid)
step 3. x + y + 90 + 140 = 360 (a quadrilateral has 360° of internal angles)
step 4. x + 90 + 90 + 140 = 360
step 5. x = 40°.
