Question

What’s the size of the missing angle

Answer 1

Answer:

Option D, 44

Step-by-step explanation:

Step 1:  Find the size of the missing angle

All triangles add up to 180 degrees.

$106 + 30 + x = 180$

Step 2:  Combine like terms

$(106 + 30) + x = 180$

$136 + x = 180$

Step 3:  Subtract 136 from both sides

$136 + x - 136 = 180 - 136$

$x = 44$

Answer:  Option D, 44

Answer 2

Answer:

44

Step-by-step explanation:

106 + 30 = 136

180 - 136 = 44
