Help me please and thank you

Answer:

x = 20

y = 10

m∡8 = 110°

Step-by-step explanation:

m∡1 + m∡2 = 180

5x + y + 3x + y = 180

8x + 2y = 180

m∡1 = m∡8    (they are alternate-exterior angles and are congruent)

5x + y = 3x + 5y

2x = 4y

x = 2y

Substitute '2y' for 'x' in 8x + 2y = 180

8(2y) + 2y = 180

18y = 180

y = 10

x = 2(10)

x = 20

m∡8 = 3(20) + 5(10) = 110°

liubo4ka [24]

Answer:

x=3

y=-4

Step-by-step explanation:

4x+5y=-8 ----------- (1)

-4x-4y=4 -----------(2)

Adding equation (1) and (2)

4x+5y-4x-4y=-8+4

y=-4

Substitute y=-4 in equation (1) or (2)

4x+5(-4)=-8

4x-20=-8\\4x=-8+20\\4x=12\\x=3
