Point A is the point of concurrency of the angle bisectors of ΔDEF. What is the length of ZA? ZA = 3cm ZA = 4cm ZA = 5cm ZA = 6c

d1i1m1o1n [39]

The picture in the attached figure

we know that
The angle bisectors of a triangle intersect in a point (incenter) that is equidistant from the three sides of the triangle
so
ZA=YA=XA-----> <span>are the radii of the inscribed circle
XA=3 cm

therefore
ZA=3 cm

the answer is
ZA=3 cm</span>

Solve this system of equations using the substitution method<br> y = 2x + 17<br> y = 6x - 3

guapka [62]

Step-by-step explanation:

well, as you can witness both of the equations are equal to y, so you're free to reckon that they are equal as well

$6x - 3 = 2x + 17 = = = > \\ 4x = 20 = = = > x = 5 \: and \: \\ y = 6(5) - 3= = = > y = 27$
