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°

Step-by-step explanation:
Answer:
7.33333 hours
Step-by-step explanation:
Theo's speed = 55mph
Distance = speed * time
Distance covered after 2 hours
Distance = 55 * 2 = 110 miles (distance already covered by Theo when Dennis left
Dennis speed = 70mph
Let time taken to catch up = x
70x = 110 + 55x
70x - 55x = 110
15x = 110
x = 110 / 15
x = 7.33333 hours
Answer:
m = 10/3
<em>(as a decimal: m = 3.333...)</em>
<em />
Step-by-step explanation:
5m - 8 = 2m + 2
5m - 8 = 2m + 2
- 2m - 2m <em>(make all "m" on one side to isolate variable)</em>
3m - 8 = 2
+ 8 + 8 <em>(get m entirely on 1 side)</em>
3m = 10
÷3 ÷3 <em>(divide by 3 to get 1m)</em>
m = 10/3
<em>(as a decimal: m = 3.333...)</em>
