Answer:
x = 32°
Step-by-step explanation:
∆KLM is an isosceles triangle because it has two equal sides, KL & KM. Therefore, the angles opposite to each of the two equal sides, which are referred to as the base angles are congruent to each other.
m<KML = m<KLM = 58°
m<MKL = 180 - (58 + 58) (Sum of triangle)
m<MKL = 64°
m<JKM = 180 - m<MKL (linear pair theorem)
m<JKM = 180 - 64 (Substitution)
m<JKM = 116°
∆JKM is also an isosceles triangle with two equal sides. Therefore, it's based angles (x & <J) would also be equal to each other.
Thus:
x = ½(180 - m<JKM)
x = ½(180 - 116) (Substitution)
x = 32°

Answer:Here are some more problems to solve.
Calculate the volume of a paperback book with the following dimensions:
Length = 12 cm
Width = 3 cm
Height = 20 cm
Calculate the volume of a steel bar with the following dimensions:
Length = 5 cm
Width = 2 cm
Height = 30 cm
Now determine the density of the steel bar if its mass is 2.34 kg. (Hint: Convert to grams first.)
