Answer:
j = 2/19
Step-by-step explanation:
Step 1: Subtract 7 on both sides
-2/j = -19
Step 2: Multiply <em>j</em> on both sides
-2 = -19j
Step 3: Divide both sides by -19
2/19 = j
If the question is -2/(j + 7) = 12:
Step 1: Multiply both sides by j + 7
-2 = 12(j + 7)
Step 2: Distribute
-2 = 12j + 84
Step 3: Subtract 84 on both sides
-86 = 12j
Step 4: Divide 12 on both sides
j = -43/6 = -7.167
Answer:
1/6 fraction is the answer
Step-by-step explanation:

So the quick answer is 64
Long answer:
First, since every triangles angles add up to 180 we can subtract 52, and get whet the combo of the others are, and it gets us 128. Now since the to legs attached to the known angle are the same, this means that the other 2 angles are also the same and this triangle is a mirror image. Thus we can just divide what we have by 2, and we get 64. And now you have the answer for both unknown angles.
Also for the other one g can be determined by a similar but reversed method, which ends up being 132
Answer:
141.78 m
Step-by-step explanation:
Let d = distance of boat from the base of the lighthouse
Tan 10 = 25/d
d tan 10 = 25
d = 25/tan 10
d = 141.78 m
