Since it's a right triangle, we know that we can use SOHCAHTOA for this.
To find a, we know it's the side adjacent to the angle, and our other given value is the opposite side, 18. We can use TOA, (Tangent of 15) x 18, or 18tan15
this is 15.1, so you can now use this concept to find b (hypotenuse), then add that all up to get the perimiter!
Let me know if this helps!

Victoria is 9. Her neighbor is 5.
Answer:
D
Step-by-step explanation:
The red graph is vertically shifted from the blue graph. Let's understand horizontal and vertical shifts.
If we have a graph of
, then
- f(x) + a is a units shifted vertically up
- f(x) - a is a units shifted vertically down
- f(x-b) is b units shifted horizontally right
- f(x+b) is b units shifted horizontally left
Since the red one is vertically shifted 3 units up (compared to blue graph), the equation would be:

Correct answer is D
Answer: 120 shrimp in a 5 pound bag.
Step-by-step explanation: For every pound there is 24 shrimp, so 2 pounds is 48
24+24=48
48+24=72
72+24=86
The equation should be 24 x 5= 120
