now solve the quadretic eq. for the value of a
I hope it help to u
Answer:
4
Step-by-step explanation)
n(3) - 5 = 7
n(3)= 7 + 5
n(3)= 12
n3/3 = 12/3
n =4
Answer:
38.6 miles
Step-by-step explanation:
The scenario has been modeled as a triangle, where A, B and C are the angles and a, b and c are the sides opposite the angles.
<u>Side c</u>
AB = 34 miles
<u>Angle B</u>
90° - 53° = 37°
<u>Angle A</u>
90° + 21° = 111°
<u>Interior angles of a triangle sum to 180°</u>
⇒ A + B + C = 180°
⇒ 111° + 37° + C = 180°
⇒ 148° + C = 180°
⇒ C = 180° - 148°
⇒ C = 32°
To find the measure of side b (AC), use the Sine Rule.
<u>Sine Rule</u>
(where A, B and C are the angles and a, b and c are the sides opposite the angles)
Substitute the values into the formula:
Therefore, weather station A is 38.6 miles from the storm.
