Question

What’s the value of x A- 86.5 B- 43.25 C- 133.25 D- 46.75

Answer 1

133.25 is the awnser for this question

Answer 2

Answer : The correct option is, (B) 43.25

Step-by-step explanation :

As we know that the sum of interior angles of a triangle is equal to $180^o$.

$\angle D+\angle F+\angle E=180^o$

The given triangle is an isosceles triangle in which the angles opposite to equal sides are always equal.

Side DF = Side EF

So, $\angle D=\angle E=x^o$

Given : $\angle F=93.5^o$

$x^o+93.5^o+x^o=180^o$

$2x^o+93.5^o=180^o$

$2x^o=180^o-93.5^o$

$2x^o=86.5^o$

$x^o=\frac{86.5^o}{2}$

$x=43.25^o$

Thus, the value of 'x' is, $43.25^o$
