Answer:
not a right triangle
Step-by-step explanation:
The Pythagorean Theorem states that If a triangle is a right triangle,
the hypotenuse^2 will equal to shorter^2 + longer^2
hypotenuse = 18, shorter side = 4, longer side = 17
18^2 = 4^2 + 17^2
324 = 16 + 289
324 = 305
That is false, therefore the triangle is not a right triangle
Answer:
A i think
Step-by-step explanation:
Answer:
y=18.5x
Step-by-step explanation:
74-55.5=18.50
92.50-74=18.50
111-92.5=18.50
(3,55.50)
y=18.5x +b
55.50=18.5(3)+b
55.50=55.50+b
b=0
Answer
Find out the the total length of the walking trail .
To prove
Formula

As given
The trail starts at R(−3, 2) and goes to S(2, 2) and continues to T(2, −5).





RS = 5 units
As given
S(2, 2) and continues to T(2, −5).
Now




ST = 7 units
Therefore
Total length of the trail = RS + ST
= 5 units + 7 units
= 12 units
Therefore the total length of the trail is 12 units.
True because tan(20)=2.1 and cot(20)=is o.44
