Answer:
Yes, the right angle is angle B
Step-by-step explanation:
we have
Plot the vertices
see the attached figure
we know that
If triangle ABC is a right triangle
then
Applying the Pythagoras Theorem
the formula to calculate the distance between two points is equal to
<em>Find the distance AB</em>
substitute in the formula
<em>Find the distance BC</em>
substitute in the formula
<em>Find the distance AC</em>
substitute in the formula
Verify the Pythagoras theorem
---> is true
therefore
Is a right triangle and the right angle is B
Answer:
Hello! answer: 13
Step-by-step explanation:
12 × 12 = 144
5 × 5 = 25
144 + 25 = 169
√169 = 13
13 × 13 = 169 therefore the length of the missing side is 13 hope that helps!
Answer:
4x-y=3
Step-by-step explanation:
IT'S standard form
It is in form (x,y) (ususally)
7.5 and 12
there is something called a coordinate system where a line called the y axis runs vertically for infinity and a line perpendicular to it, crosses it. the other line is called the x axis which also extends for infinity
the point where they cross is point (0,0) or the origin
basically the numbers tell you how far you are from the axises
on the y axis, + numbers are up and - numbers are down
on the x axis, + numbers are to the right and - numbers are to the left
7.5=x and 12=y
+7.5 is positive
7.5 means that the point is 7.5 units to the right of the origin in relation to the x axis
12 is positive
12 means that the point is 12 units up from the origin in relation to the y axis
hope this helped. feel free to ask if its too confusing
Answer/Step-by-step explanation:
a. Unknown side, b, using the Pythagorean theorem is solved as shown below.
Unknown side, b, = 36 km
b. Perimeter of the triangle = sum of all the sides of the ∆ =
c. Area of triangle = ½*base*height
where,
Base = 36 km
Height = 27 km
