2 answers:
Answer:
answer is: 45.238%
Step-by-step explanation:
Let the total population be 'x'
The percent population of student that own both smartphone and a tablet=38%
That means the number of students owing both smartphone and tablet=
Also, 84% of total students own a smart phone
That means the number of students owing smartphone=
Now, we need to find the percent of students who own a smartphone also own a tablet:
percentage student
Hence, the percent students who owns a smartphone also own a tablet=45.238%

The isosceles triangle is proved below.
<h3>How to illustrate the triangle?</h3>The complete information wasn't found. The proofing of the triangle will be illustrated. It should be noted that the angles opposite to the equal sides of an isosceles triangle are also equal.
Proof: Consider an isosceles triangle ABC where AC = BC.
We need to prove that the angles opposite to the sides AC and BC are equal, that is, ∠CAB = ∠CBA.
We first draw a bisector of ∠ACB and name it as CD.
Now in ∆ACD and ∆BCD we have,
AC = BC (Given)
∠ACD = ∠BCD (By construction)
CD = CD (Common to both)
Thus, ∆ACD ≅∆BCD (By SAS congruence criterion)
So, ∠CAB = ∠CBA (By CPCT)
