Find the length of AC on this triangle
Illusion [34]

Answer:

A

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan12° = \frac{opposite}{adjacent} = \frac{AC}{BC} = \frac{AC}{44} ( multiply both sides by 44 )

44 × tan12° = AC , then

AC ≈ 9.35 ( to 2 dec. places )

Find the missing angles for each problem, given that lines a and b are parallel (step by step)
marshall27 [118]

Answer:

1) 40°

2) 140°

3) 140°

5)40°

6)140°

7)140°

8)40°

Step-by-step explanation:

1 = 40 °        <em>  [Vertically Opposite angles are equal]</em>

8 = 40 °         <em>[Corresponding Angles are equal]</em>

5 = 8 = 40°  <em> [Corresponding Angles are equal]</em>

7 = 180° - 40° = 140°      <em>[Supplementary angles sum 180°]</em>

6 = 140°           <em> [Vertically Opposite angles are equal]</em>

2 = 140°            <em>[Corresponding Angles are equal]</em>

3 = 140 °          <em> [Vertically Opposite angles are equal]</em>
