Answer:
∠BAD = 109°
∠DAC = 111°
Step-by-step explanation:
This is essentially a triangle, correct? Something to know is that these angles in a triangle add up to 360°.
In mathematical terms, this would look like: 140 + (2x + 4) + (2x + 6) = 360
Now, we solve for x.
140 + (2x + 4) + (2x + 6) = 360 (Subtract 140 from both sides to get x's on one side)
2x + 4 + 2x + 6 = 220 (Add like terms: 2x + 2x and 4 + 6)
4x + 10 = 220 (Subtract 10 from both sides to get x on one side)
4x = 210 (Divide both sides by 4 to get x by itself)
x = 52.5
Now that we know what x equals, we can plug it in to find ∠<em>BAD</em> and ∠<em>DAC</em>.
2x + 4 → 2(52.5) + 4 = 109
2x + 6 → 2(52.5) + 6 = 111

Step-by-step explanation:
Answer:
Distance B = 1275 kilometers.
Step-by-step explanation:
Let the two distances and time be A and B respectively.
Given the following data;
Distance A = 17 kilometers.
Time A = 8 minutes.
Distance B =?
Time B = 60 minutes.
First of all, we would find the constant speed;
Speed = distance/time
Substituting into the equation, we have;
Speed = 17/8
Speed = 2.125 km/m
Now, to find the distance B;
Distance B = speed * time
Distance B = 2.125 * 60
<em>Distance B = 1275 km</em>
The answer is 3/7
