The length of AC is 16 km.
Solution:
Given data:
AB = c = 14 km, ∠A = 30° and ∠B = 89°
AC = b = ?
<u>Let us first find angle C:</u>
<em>Sum of all angles in a triangle = 180°</em>
m∠A+ m∠B + m∠C = 180°
30° + 89° + m∠C = 180°
119° + m∠C = 180°
Subtract 119° from both sides, we get
m∠C = 61°
<u>To find the length of AC:</u>
<em>Using sine formula:</em>
Substitute the given values in the formula.
Multiply by sin 89° on both sides.
The length of AC is 16 km.
Answer:
B) Yes, because the slope is and the zero is (12, 0)
Step-by-step explanation:
From inspection of the graph:
- y-intercept = (0, 100)
- Two points: (3, 75) and (6, 50)
Therefore, the equation of the line in slope-intercept form y = mx + b
(where m is the slope and b is the y-intercept) is:
To find the zero (when y = 0), set the equation to zero and solve for x:
Therefore, the zero is at (12, 0)
Therefore, the graph does represent the function because the slope is and the zero is at (12, 0)
