Answer:
∠1 = 70°
Step-by-step explanation:
The three marked angles are vertical angles with the interior angles of a triangle. Vertical angles are congruent, hence the sum of the marked angles is 180°.
∠1 = 180° -60° -50° = 70°
The answer is 1253/10,000
<em>x = - 2</em>
- <em>Step-by-step explanation:</em>
<em>Hi there ! </em>
<em>5x - 6 = - 16</em>
<em>5x = - 16 + 6</em>
<em>5x = - ( 16 - 6)</em>
<em>5x = - 10</em>
<em>x = - 10 : 2</em>
<em>x = - 2</em>

This way Sally travels 12+9=21 kilometers.
If there was a direct way she could go to work, that way would have been 15 km (because her way to work forms a right-angled triangle).
Therefore her journey would be 21-15=6 km shorter. Choice A.
