Answer: The penguin will walk 75.15 feet in 45 sec
Answer:
x = 7 , y = 7
Step-by-step explanation:
A 45- 45- 90 triangle is an isosceles right triangle with the 2 legs being congruent , that is
x = 7
Using Pythagoras' identity in the right triangle, then
y² = 7² + 7² = 49 + 49 = 98 ( take square root of both sides )
y =
=
=
×
= 7
Answer:
Step-by-step explanation:
cot = cos / sin
tan = sin / cos
=> sin²A × cos²A/sin²A + cos²A × sin²A/cos²
=> cos²A + sin²A
=> 1
Answer:

Step-by-step explanation:
If it has a slope of 3/4, then it will look like this:

If it passes through (4, 0), than y = 0 when x = 4



Therefore, the equation is
.
