Answer:
9.4cm
Step-by-step explanation:
by pythagoras theorem,
a^2 + b^2 = c^2
5^2 + 8^2 = c^2
c^2 = 89
c = √89 = 9.433981 ≈ 9.4
The answer to your problem is a^67b^76
Answer:
x = 12
m(∠B) = 45°
Step-by-step explanation:
Given question is incomplete; find the complete question in the attachment.
In the figure attached two lines 'l' and 'm' are the parallel lines and line 'n' is a transverse.
Angles A and B are the "Alternate exterior angles" which will equal in measure.
m(∠A) = m(∠B)
(5x - 15) = (2x + 21)
5x - 2x = 15 + 21
3x = 36
x = 12
Since, m(∠B) = (2x + 21)
= (2×12) + 21
= 24 + 21
= 45°
Therefore, x = 12 and measure of angle B will be 45°.
If b equals three
3 subtract 2
Equals one
Answer:
B: A square
Step-by-step explanation:
Let's use the process of elimination:
We know that each shape here has opposite parallel sides so there's not much we can do about that one.
All sides congruent automatically gets rid of A.) Rectangle and C.) Parallelogram because they do not <em>always</em> have congruent sides
Opposite angles are congruent gets rid of D.) Rhombus. Although a rhombus can have all congruent angles, it isn't <em>always</em> congruent the way a square is. The definition of a rhombus is a quadrilateral with <em>equal side lengths</em>. Not angles.
So the only shape that meets each criteria all the time is a square.
