Answer:
3
Step-by-step explanation:
it's just the cubed root of 27 which is 3 because 3 x 3 x 3 equals 27
Answer:
XG segment is an angle bisector of ∠YXZ ⇒ C
Step-by-step explanation:
Let us revise the steps of constructing a bisector of an angle
- Place compass pin on the vertex of the angle (point X).
- Open the compass to a suitable length that and draw an arc to intersect the two sides of the angle at two points (points E and F)
- Place the compass pin on one of these new points on the sides of the angle(point E). Stretch the compass to a sufficient length and draw an arc in the interior of the angel
- Without changing the span on the compass, place the pin of the compass on the other intersection point on the side of the angle (point F) and make a similar arc. The two small arcs in the interior of the angle are intersecting. in a point (point P)
- Join the vertex of the angle (point X) to this intersection of the two small arcs (point P) XP is the bisector of angle X
By comparing these steps with The steps in the figure, you will find that they are the same steps
∵ XP ray intersect YZ segment at G
∴ G belong to XP ray
∵ XP ray is the bisector of ∠YXZ
∴ XG segment is the bisector of ∠YXZ
Then the statement must be true is:
XG segment is an angle bisector of ∠YXZ
Answer:
t = 139/490 + sqrt(75671)/490 or t = 139/490 - sqrt(75671)/490
Step-by-step explanation:
Solve for t:
4.9 t^2 - 2.78 t - 1.15 = 0
4.9 t^2 - 2.78 t - 1.15 = (49 t^2)/10 - (139 t)/50 - 23/20:
(49 t^2)/10 - (139 t)/50 - 23/20 = 0
Multiply both sides by 10/49:
t^2 - (139 t)/245 - 23/98 = 0
Add 23/98 to both sides:
t^2 - (139 t)/245 = 23/98
Add 19321/240100 to both sides:
t^2 - (139 t)/245 + 19321/240100 = 75671/240100
Write the left hand side as a square:
(t - 139/490)^2 = 75671/240100
Take the square root of both sides:
t - 139/490 = sqrt(75671)/490 or t - 139/490 = -sqrt(75671)/490
Add 139/490 to both sides:
t = 139/490 + sqrt(75671)/490 or t - 139/490 = -sqrt(75671)/490
Add 139/490 to both sides:
Answer: t = 139/490 + sqrt(75671)/490 or t = 139/490 - sqrt(75671)/490
