Answer:
15 answers
Step-by-step explanation:
To solve this question we need to set up an equation.
Let's name the number of incorrect answers x.
<u>We can set up an equation that's essentially:</u>
(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score
When we plug in our numbers and variables it looks like this:
5(3)+(-2x)=-15
Simplify
15-2x=-15
Subtract 15 from both sides
-2x=-30
Divide both sides by -2
x=15
This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.

Answer: x = 44</h3>
====================================================
Work Shown:
The three interior angles of any triangle always add to 180
82+54+x = 180
136+x = 180
x = 180-136
x = 44
---------------
Extra info:
If you need the value of y, then,
x+y = 180
y = 180-x
y = 180-44
y = 136
Or you could use the remote interior angle theorem to find y
y = 82+54
y = 136
The value of z is equal to y since these two angles are vertical angles.
Based on the definition of bisection and appropriate theorems, the proof that shows ΔABE ≅ ΔCDE is shown below.
<h3>What is the Definition of Bisection?</h3>
When two lines bisect each other, they divide each other into equal segments, that is congruent segments.
The proof that shows that triangles ABE and CDE are congruent is explained below:
<u>Statement Reasons </u>
1. BD and AC bisect each other 1. Given
2. AE ≅ CE and BE ≅ DE 2. Definition of bisection
3. ∠AEB ≅ ∠CED 3. Vertical angles theorem
4. ΔABE ≅ ΔCDE 4. SAS congruence theorem
