Answer:
387 km
Step-by-step explanation:
The length of AC, b can be obtained using the cosine rule ; using the cosine relation:
b² = a² + c² - 2ac CosB
b² = 250² + 185² - 2(250*185) Cos125
b² = 62500 + 34225 - 92500 * −0.573576
b² = 96725 + 53055.820
b² = 149780.82
b = sqrt(149780.82)
b = 387.01527
b = 387 km (nearest whole number)
Answer:
17155
Step-by-step explanation:
23500-27%-17155
To the nearest hundred: 17200.
Step-by-step explanation:
By cross multiplication,
→ 83(5) = 4x(7)
→ 415 = 28x
<h3>→ 415/28 = x</h3>
