Find the value of X in the triangle shown below

102°

Step-by-step explanation:

Since the triangle is an isosceles triangle, two sides are equal and angle opposite to them are also equal.

Therefore, x°+39°+39°=180°

=> x°+78° = 180°

=> x° = 180-78° = 102°

25

step-by-step explanation:

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
