Answer:

  • 65° if parallelogram
  • 115° if trapezoid

Step-by-step explanation:

<em>Since no diagram attached there are two possible options.</em>

Option 1

The quadrilateral is parallelogram.

<u>In this case ∠A and ∠D sum up to 180°, therefore:</u>

  • ∠ADC = 180° - 115° = 65°

Option 2

The quadrilateral is isosceles trapezoid.

<u>In this case ∠A is congruent with ∠D, therefore:</u>

  • ∠ADC = ∠A = 115°

Step-by-step explanation:

Since sides AD and BC are parallel,

Angle BAD + Angle ADC = 180° (co-interior angles)

Therefore Angle ADC = 180° - 115° = 65°.

Step-by-step explanation:

width= w

length = l=w+5

Area = l * w

104 =(w+5) * w

w2 +5w -104 =0

(w+13)(w-8)=0

w=13 and w=8

so width =8

length=13

– 36 – m = 8(4 + 2m)
valentina_108 [34]

Answer:

m = -4

Step-by-step explanation:

- 36 - m = 8(4+2m)

- 36 - m = 32+16m (to remove m from the left side, we need to add m to both sides)

- 36 = 32+17m (subtract 32 from both sides)

- 68 = 17m (divide by 17 on both sides)

-4 = m
