Answer:
D:21
Step-by-step explanation:
Use the vertical angles equation.
4x + 13 = 5x - 8
Subtract 4x from 5x.
5x - 4x = x
13 = x - 8
Add 8 on both dies.
13 + 8 = 21
x = 21
JKLM has x that equals 21.
<JKLM and <LMJK equal 97 degrees.

Answer:
See the procedure
Step-by-step explanation:
we know that
<u>The Triangle Inequality Theorem</u>, states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side
Let
a,b,c the lengths side of triangle
c is the greater side
The perimeter is equal to
P=a+b+c
P=36 cm
If c=18 cm
then
a+b=18
Applying the Triangle Inequality Theorem
a+b > c
18 > 18 ----> is not true
therefore
Principal Aranda is incorrect
The larger side cannot measure 18 cm
The largest side must be less than 18 cm
9°, complementary angles always add up to 90°
I got 70
Combination=n!/((n-r)!r!)
=8!/((8-4)!*4!)
=8*7*6*5*4!/(4!*4!)
=8*7*6*5/(4*3*2)
=70 ways
