If tan 0= 12/5 and cos 0= -15/3 , then what is sin 0

love history [14]

Answer:

sin0 = -12

Step-by-step explanation:

tan0 = sin/cos

12/5 = sin / -15/3

sin = tan0 x cos0 = 12/5 x -15/3 = -12

Nostrana [21]

Use proportions.
214/236=x/100(100 because it's a percentage.
cross multiply:
23600=214x
solve for x:
x= 11.3(rounded)
11.3% increase

Draw a diagram in which segment AB intersects segment CD equals segment CB

Contact [7]

The <u>correct diagram</u> is attached.

Explanation:

Using technology (such as Geogebra), first construct a line segment. Name the endpoints C and D.

Construct the perpendicular bisector of this segment. Label the intersection point with CD as B, and create another point A above it.

Measure the distance from C to B and from B to D. They will be the same.

Measure the distance from A to B. If it is not the same as that from C to B, slide A along line AB until the distance is the same.

Using a compass and straightedge:

First construct segment CD, being sure to label the endpoints.

Set your compass a little more than halfway from C to D. With your compass set on C, draw an arc above segment CD.

With your compass set on D (the same distance as before) draw an arc above segment CD to intersect your first arc. Mark this intersection point as E.

Connect E to CD using a straightedge; mark the intersection point as B.

Set your compass the distance from C to B. With your compass on B, mark an arc on EB. Mark this intersection point as A.

AB will be the same distance as CB and BD.
