In triangle $ABC,$ $AB = BC = 17$ and $AC = 16.$ Find the circumradius of triangle $ABC.$
sweet-ann [11.9K]

Answer:

R = 9.63\ units

Step-by-step explanation:

Given

AB = BC = 17

AC = 16

Required

Determine the circumradius, R

The circumradius is calculated as follows;

R = \frac{AB * BC * AC}{\sqrt{(AB + BC + AC)(AB + BC - AC)(AB + AC - BC)(AC + BC - AB)}}

Substitute the values of AB, BC and AC

R = \frac{17 * 17 * 16}{\sqrt{(17 + 17 + 16)(17 + 17 - 16)(17 + 16 - 17)(16 + 17 - 17)}}

Evaluate the denominator

R = \frac{17 * 17 * 16}{\sqrt{(50)(18)(16)(16)}}

R = \frac{4624}{\sqrt{230400}}

Take square root of 230400

R = \frac{4624}{480}

R = 9.63\ units <em>(Approximated)</em>

<em>Hence, the circumradius is 9.63</em>

VladimirAG [237]
First, we must calculate the weekly pay of an employee that is paid a fixed amount. Given that there are 52 weeks in a year, the weekly pay for a regularly paid employee is: 67,000 / 52 = $1,288.46 Now, we calculate the number of hours an employee that is paid hourly works per week: 0 + 10 + 8 + 8 + 7 + 6.5 + 4.5 = 44 So this employee is paid: 25 x 40 + 37.5 x 4 = $1,150 Therefore, it is recommended that a new employee goes for the salaried pay since the weekly earnings are greater in this option. The answer is C<span>.</span>
