Answer:
C.) 4
Step-by-step explanation:
we are given ABCD is an isosceles trapezoid
AB || CD
AB = m + 6
CD = 3m + 2
BC = 3m
AD = 7m - 16
Since, ABCD is an isosceles trapezoid
so, two sides must be equal
now, we can plug values
now, we can solve for m
Divide both sides by -4
and we get
Presumably, ln⁵(<em>x</em>) is the same as (ln(<em>x</em>))⁵ (as opposed to a quintuply-nested logarithm, log(log(log(log(log(<em>x</em>)))))).
Then substituting <em>u</em> = ln(<em>x</em>) and d<em>u</em> = d<em>x</em>/<em>x</em> gives
Answer:
Step-by-step explanation:
The interior angles of a triangle must add to 180 degrees.
Let's add the three angles we are given and see what the sum is.
- The three angles are 127, 38, and 15
Add them together.
- 127+38+15=180
- 3 angles = 180 degrees
The three angles equal 180 degrees, therefore they can create a triangle.
