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:
C
Detailed explanation down below
Step-by-step explanation:
A bisector divides an angle in half, so we can say that:
7x - 27 = x + 57
7x = x + 84
6x = 84
x= 14
So now lets input this information
7 x 14 - 27 = m∠ LMO = 98 - 27 = 71°
14° + 57° = 71°
(Actually we didnt have to do this second equation because both angles should be equal.)
71° + 71° = 142°
So the answer is C : x=14° . m∠LMN = 142°

Step-by-step explanation:
~~~~~~~~~~~~~~~~~~~~~
USE THIS TO GET "B"
the f(-b/2a) is the highest point,
the vertex of the parabola [-b/2a, f(-b/2a)] will give you the time
and height of the highest point
~~~~~~~~~~~~~~~~~~~
USE THIS TO GET "A"... you will get two answers one will be negative
ignore that one , the positive one is the time to hit the ground
if you factor the equation (use the quadratic formula) you will get
the "zeros" that is where the ball is on the ground...
~~~~~~~~~~~~~~~~~~~~~~~
THIS IS FOR PART "C"
if you set the equation equal to 4.5 meters and factor that for the "zeros" you will get the two times that the ball is at that height.. subtract the two times for the duration
