Answer:
Infinitely many
Step-by-step explanation:
for example,
a triangle of 1 - 1 - 
is 45 - 45 - 90 based on the 45-45-90 triangle theorem
if I multiply the three side lengths listed above by the same number, I will still have a 45 -45 -90 because of the definition of similar triangles
Answer:
x = 1/3
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other:
21x = 7
Divide 21 from both sides:
(21x)/21 = (7)/21
x = 7/21
x = 1/3
x = 1/3 is your answer.

Answer:
The midpoint of CD is (3, 2)
Step-by-step explanation:
The movement of x is +2 from C to D and the movement of y is 16 from C to D
2 (C's x coordinate) +2/2 (to find the movement up to the x coordinate of the midpoint) and -6 (C's y coordinate) + 16/8 (to find the movement up to the y coordinate of the midpoint)
This is 2+1 as the x coordinate and -6+8 as the y coordinate that is (3, 2)
Answer: 76.35in²
Step-by-step explanation:
Circumference of a circle = 2πr or πd , while area is πr².
To find the area we must first of all find the radius if the circle using any of the formula above.we then equate 31 to 2πr and then solve for r.
31 = 2πr , where π = 3.142 or 22/7
r = 31/2 x 3.142
= 31 /6.284
= 4.93in
To find the area, substitute for r in the formula above,
Area = πr²
= 3.142 x 4.93²
= 3.142 x 24.30
= 76.35in².
