The vertex angle of an isosceles triangle measures 26° . The base is 30 units long. What is the length of a leg of the isosceles
sergejj [24]

Answer:

65.46 units

Step-by-step explanation:

Given the information:

  • The vertex angle of an isosceles triangle measures 26°

=> the leg angle is:

= (180°  - 26° )/2

= 77°

  • The base is 30 units

Let x is the length of the leg side (x>0)

We use cosine law to find x, we have:

30^{2} = x^{2} +x^{2} -2xxCos(26) Because the  isosceles has two equal leg sides

<=> 30^{2} = 2x^{2} - 1.79x^{2}

<=> 0.21x^{2}  = 30^{2}

<=> x^{2} =4285

<=> x = 65.46 units

Hope it will find you well.
