Answer:
B only
Step-by-step explanation:
In A and in C, only the angles of
one triangle are congruent to the
corresponding angles of the other
triangle. That proves similar triangles but
not necessarily congruent triangles.
Definition of congruent triangles:
Two triangle are congruent if all angles
of one triangle are congruent to all
corresponding angles of the other
triangle and all sides of one triangle are
congruent to all corresponding sides of
the other triangle.
That happens only with the triangles in B.
Answer: B only
Answer:
(-10, 10) and (0,10).
Step-by-step explanation:
For a point to be a solution to the system of inequalities, you will need to see which of the points falls into the shaded area.
When we test out each of the points, we can see that only:
(-10, 10) and (0,10) fall into the blue-shaded area.
Always use PEMDAS as order of operations:
parentheses before exponents before multiplication before division before addition before subtraction = P.E.M.D.A.S.
Since we have only addition, subtraction, multiplication, and division, we need to do:
M>D>A>S
5 + 5 - 2 * 7 / 8 + 98 - 64
5 + 5 + [-2 * 7] / 8 + 98 - 64. first
5 + 5 + [-14 / 8] + 98 - 64. second
(10) + [-1.75 + 98] - 64. third
[10 + 96.25] - 64. fourth
106.25 - 64. last
42.25

Answer:
b = 30 degrees
a = 150 degrees
Step-by-step explanation:
Let's call <em>a</em> to the first angle and <em>b</em> to the second one. So we have:
a = 5*b (1)
and it says that the greater angle has 120 degrees more than the lesser angle. So It will be:
a = 120+b (2)
We just need to solve both equations. We can equal both of them.
5b = 120+b
4b = 120
b = 30 degrees
Therefore a = 5*30 = 150 degrees
a = 150 degrees
