Answer:

a = 1

Step-by-step explanation:

Given

4x - 3(x + a) = 2

x  = 5

Required

Determine the value of a

4x - 3(x + a) = 2

Substitute 5 for x

4(5) - 3(5 + a) = 2

Open all brackets

20 - 15 - 3a = 2

5 - 3a = 2

Collect Like Terms

-3a = 2 - 5

-3a = -3

Solve for a

a = -3/-3

a = 1

I do not need an explanation, just a simple angle number!
Murljashka [212]

Answer:

Step-by-step explanation:

a + 143 = 180    {Linear pair}

a = 180 - 143

a = 37

37 + 93 + b = 180 {Angle sum property of triangle}

130 + b = 180

         b = 180 - 130

         b = 40

c + b = 90

c  + 40 = 90

c = 90 - 40

c = 50

d + 120 = 180   {Linear pair}

d = 180 - 120

d = 60

? = 60 + 40         {Exterior angle property of triangle}

? = 100
