Answer:
On the trig unit circle,
tan 225 = tan (45 + 180) = tan 45 = 1
True
If all sides of a triangle are congruent with those of another triangle, the triangles are congruent. SSS is an abbreviation or mnemonic for side-side-side, telling you what must be congruent in order for this postulate to apply.
Answer:
(-3,8)
Step-by-step explanation:
Given the coordinates of the endpoints of EF are E( – 9,11) and F(1,6). Point G is on EF and divides it such that EG:FG is 2:3.
Coordinate of G is expressed as shown;
X = ax1+bx2/a+b
X = -9(2)+3(1)/2+3
X = -18+3/5
X = -15/5
X = -3
Similarly;
Y = ay1+by2/a+b
Y = 2(11)+6(3)/2+3
Y = 22+18/5
Y = 40/5
Y = 8
Hence the coordinate of point G is at (-3,8)
