Answer:
35.7 km and 248.3 °
Step-by-step explanation:
I will attach the diagram to an image to make it easier to understand.
We will use the formula corresponding to the law of cosine
y² = 42² + 28² - (2 * 42 * 25 * cos 58 °)
y² = 2389 - 1112.83 = 1276.17
y = √1276.17
y = 35.72 km
Now, to calculate the surveyor's bearing from her base camp we must use the sine law:
[(Sin 58 °) / y] = [(Sin A) / 42]
Without A = (42 * without 58 °) /35.72
A = sin⁻¹ (0.9971)
A = 85.7 °
Bearing of the surveyor from the base camp = 270 ° - (85.7 ° - 64 °) = 248.3 °

Answer:
4,5 and 6
Step-by-step explanation:
because they repeat the most times and they are repeated the exact same amount
70% = 0,7 = 7/10
7/10 * x = 35 | (*10/7)
7/10 * 10/7 * x = 35/1 * 10/7 7/10 * 10/7 => 1
1x = 35/1 * 10 / 7
x = (35*10)/7
x = 350 / 7
x = 50
