Answer:
a = sqrt(b^2 + c^2 - 2bc cosA) = sqrt(13^2 + 6^2 - 2 * 13 * 6 * cos 50) = sqrt(169 + 36 - 156 cos 50) ≈ sqrt(205 - 100.3) ≈ sqrt(104.7) ≈ 10.2
a ≈ 10.2
c / sin C = a / sin A
sin C = c sin A / a = 6 sin 50 / 10.2 ≈ 0.4491
C = arcsin(0.4491) ≈ 26.7
C ≈ 26.7°
B = 180 - A - C ≈ 180 - 50 - 26.7 ≈ 103.3
B ≈ 103.3°
Step-by-step explanation:
Answer:
Step-by-step explanation:
The top angle = 90° - 29° = 61°
Sin 61° = opp/hyp
Sin 61 = x/500
x = 500 × sin 61°
X = 437.3ft
Answer:
Your equation option is possibly in here somewhere.
Step-by-step explanation:
A = <em>C - 2</em>
B = A + 6 → A = <u>B - 6 </u>
<em>C - 2</em> = A = <u>B - 6</u> → B = <u><em>C + 4</em></u>
44 = C + B + A
44 = C + (<u><em>C + 4</em></u>) + (<em>C - 2</em>)
44 = 3C + 2
42 = 3C
C = 7
