Mathematics
1 answer:
Zina [86]3 years ago
5 0
Here is your answer

\huge x=\frac{35}{2}cm= 17.5cm

REASON :
AB//CD

So,

/_A=/_D ... (alternate int. angles)

/_B=/_C ... (alt. int. angles)

So,

Tri.ABE~Tri.DCE... (by AA similarity)

Therefore,

Corresponding sides are proportional

i.e.

\frac{AE}{DE}=\frac{AB}{DC}

\frac{5}{x}=\frac{4}{14}

x=\frac{5×14}{4}

x=\frac{5×7}{2}

x=\frac{35}{2}

HOPE IT IS USEFUL

The sum of two numbers is fourteen. One number is two less than three times the other. Find the numbers.
Margarita [4]
So, for the first variable, you would use x, and for the second, y. Then, you would write out 2-(3y)=14. once this is done, youd simplify to 2-3y=14. Subtract 2 from both sides to get 3y=12. Then, divide both sides by 3. this will leave you with y=4. From this you can see the other number is ten. Hope this helped! and i apologize if it is incorrect!
