Okay ...
you do the opposite
so you do
38-15=23
that would leave you with
7x=23
you then get x on its own by dividing 7x by 7
and because you divided one side yo must divide the other ..
so
23/7 =
3.2857
x=3.3
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:
Step-by-step explanation:
hey watch it fatty
The solution is x=6 and y=5
Step-by-step explanation:
When w = -2 and p = -6,
7w + 9p = 7(-2) + 9(-6) = (-14) + (-54) = -68.
