What is the measure of the vertex angle of an isosceles triangle if one of its base angles measures 73° and its congruent sides each measure 15 cm?

The measure of the vertex angle will be 34°

Step-by-step explanation:

As isosceles triangle have two equals sides and two equals angle. The two equals angle are the base angles b. We know that the sum of the angle of a triangle is 180°:

v+b+b=180°

v+2b=180°

Where v is the vertex angle. If we know the value of the base angles is 73° then the remaing vertex angle will be calculated by solving for a in the equation above:

v=180°-2*73°

v=180°-146°=34°

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.
