Answer:
A triangular scarf is an isosceles right triangle.
Step-by-step explanation:
Given: A scarf is a triangle with two perpendicular sides that are the same length.
We have to name which two terms describe a triangular scarf.
Isosceles triangle is a triangle with length of two of its sides equal.
Right angled triangle is a triangle in which one angle is a right angle.
Given :
The two sides of scarf are perpendicular to each other.
Thus, the angle formed between them is 90°. Hence, right angled triangle.
Also, length of two sides are same, Hence isosceles triangle.
Thus,a triangular scarf is an isosceles right triangle.

Answer:
y = 3x² - 42x + 144
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
here (h, k) = (7, - 3), thus
y = a(x - 7)² - 3
To find a substitute (9, 9) into the equation
9 = 4a - 3 ( add 3 to both sides )
12 = 4a ( divide both sides by 4 )
a = 3
y = 3(x - 7)² - 3 ← in vertex form
Expand factor and simplify
y = 3(x² - 14x + 49) - 3
= 3x² - 42x + 147 - 3
= 3x² - 42x + 144 ← in standard form
Answer:
e = 16
Step-by-step explanation:
-5/6e - 2/3e = -24
-5/6e + -2/3e = -24
-3/2e = -24
e = 16
Answer:
h = √(44) ft
Step-by-step explanation:
Just looked back and A is actually the area because the unit was ft².
Area of a right isosceles triangle is half the area of a square.
A = ½S²
in this case your side is h.
A = ½h²
2A = h²
√(2A) = h
√(2(22)) = h
√(44) = h
plug that in your calculator for the answer.
