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>

Distributive property/collecting like terms. 4n -2 - 2n

marusya05 [52]

Distributive property: a(b + c) = ab + ac

4n - 2 - 2n = 2(2n - 1 - n)

4n - 2 - 2n = 2n - 2 = 2(n - 1)

Using Postulates and/or Theorems, determine whether ABC~AXY.

Xelga [282]

Answer:

They are not similar

Step-by-step explanation:

To see whether the triangles are similar or not we can compare their side lengths:

AB = 24

AX = 6

AX/AB = 1/4 is the ratio now let's compare this to AY/AC

AY/AC = 10/25 if we simplify this the result will be 2/5 as we can see the side lengths are not proportional so the triangles are not similar.

What is the value of the expression 1/2(6x9x1)+15

Vanyuwa [196]

Answer:

the answer of the expression is 42

Step-by-step explanation:

PEMDAS parenthesis are first so we start out with 6x9x1 and the answer to that is 54, next is MULTIPLICATION so we take 1/2 times 52 which is 27 then next is ADD so we add 15 and the answer is 42
