Point Y is the circumcenter of triangle DEF. Point Y is the circumcenter of triangle D E F. Lines are drawn from the points of the triangles to point Y. Lines are drawn from point Y to the sides of the triangle to form right angles and line segments Y L, Y M, and Y N. The line segments cut the sides of the triangles into 2 equal parts. Which statement is true about point Y? Point Y is the center of the circle that passes through points D, F, and N. Point Y is the center of the circle that passes through points M, N, and E. Point Y is the center of the circle that passes through points L, M, and N. Point Y is the center of the circle that passes through points D, E, and F.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

3a-24=0

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
