Solve for x, y, and all the missing angles

a = 90

b = 40

c = 60

d = 30

x = 18

y = 14

Step-by-step explanation:

90 + d + c = 180

90 + 2y + 2 + 3y + 18 = 180

5y + 110 = 180

5y = 70

y = 14

d)

2y + 2

2(14) + 2

30

c)

3y + 18

3(14) + 18

60

a)

a + 90 = 180

a = 90

b)

a + b + 50 = 180

90 + 2x + 4 + 50 = 180

2x + 144 = 180

2x = 36

x = 18

2x + 4

2(18) + 4

40

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
