Answer: n is 3
Step-by-step explanation: n can only be 3 as a triangle is the only polygon whose internal angles have a sum of 180 degrees
Answer:
a triangle with an angle of 90°
a triangle with an angle of 55°
a triangle with an angle of 35°
Step-by-step explanation:
Every triangles angles add up to 180°. Add the choices up:

Each of the answers is an angle measure of the triangle.
Answer:
2744 Rhinos will be left after 10 years
Step-by-step explanation:
This question has to do with exponential decay rate. We solve this using the formula:
P(t) = Po(1 - r)^t
Where P(t) = Amount left after t years
Po = Initial amount
r = Decay rate = 3.7% = 0.037
t = time in years = 10 years
P(t) = 4000(1 - 0.037)¹⁰
P(t) = 4000 × 0.963¹⁰
P(t) = 4000 × 0.6859032667003232
P(t) = 2743.6130668
Approximately = 2744 Rhinos will be left after 10 years
Answer: 50
Find the area of the triangles then multiply by 2.
1/2 x 5 x 10 = 25
25 x 2 = 50
