Answer:

x = 70°

Step-by-step explanation:

Since 2 sides are marked as congruent then the triangle is isosceles with 2 base angles being congruent , both 55°

the sum of the 3 angles in the triangle = 180° , so

x + 55° + 55° = 180°

x + 110° = 180° ( subtract 110° from both sides )

x = 70°

Maristella is constructing an isosceles triangle to use as a model in her Algebra class. The perimeter of her triangle is 24 cm.
Vlada [557]

Isolating s, the equation written in terms of s is:

s = 12 - 0.5b

-------------------------

  • The equation for the length of the third side, as stated in the problem,("Maristella uses the equation b = 24 – 2s to find b, the length of the triangle's third side") is:

b = 24 - 2s

  • To solve for the lengths of the congruent sides, we isolate s, thus:

b = 24 - 2s

2s = 24 - b

Inverse of multiplication is division, thus:

s = \frac{24 - b}{2}

Separating into two fractions:

s = \frac{24}{2} - \frac{b}{2}

Solving each fraction:

s = 12 - 0.5b
