Find the value of x and the value of y.
kodGreya [7K]

Answer:

6√3 = x           y =12

Step-by-step explanation:

Since the two sides of the triangles have equal angles then two sides have equal length

the sum of interior angles of triangles is 180° then the last angle is 60°

then the triangles have perfect sides of 12

y = 12

to calculate x

sin Ф = opposite/hypothenus

sin 60° = x/12

sin 60° = √3/2

( √3/2 )  x 12  = x

6√3 = x

The midpoint of DG is M(-1,5). One endpoint is D(1,4). Find the
irina1246 [14]

Answer:

G(-3, 6)

Step-by-step explanation:

midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )

Substitute the coordinates of M and D into the formula:

( - 1,5) = ( \frac{x1 + 1}{2} , \frac{y1 + 4}{2} ) \\- 1=\frac{x1 + 1}{2}& ,&5&=  \frac{y1 + 4}{2} & \\ - 1(2)= x1 + 1&, & 5(2) &= y1 + 4  &\\  - 2= x1 + 1&, &10 &= y1 + 4 &\\   x1=  - 2 - 1&,& y1 &= 10 -  4 &\\  x1=  - 3&, &y1& =6  \:  \:  \:  \:  \:  \:  \:  \:  \:  \: &

Thus, the coordinates of G is (-3,6).
