What is the measure of the angle in standard position?

Mathematics
1 answer:

3 0

Answer:

Step-by-step explanation:

What's inside the set of parenthesis is a description of the angle in terms of cos and sin.  This says that the angle has a cos of square root of 3 over 2, and a sin of negative 1 over 2.  

The cos of this angle is the line directly horizontal ON the x axis, since cos is the same as x.

The sin of this angle is the line that would be there if you dropped an altitude from the arrow on the x line to the arrow on the other line.

The tangent ratio, being side opposite over side adjacent will give us the angle we need.  Use the inverse tangent and enter in those values and you'll get that the angle is -30.  

OR

even easier than that, look at your unit circle to see where there is a cos, sin combination of those values.  It will be located at -30 degrees, which is also 330 degrees.

Which point is on the line that passes through (0,6) and is parallel to the given line? plzz helppp!
Grace [21]

Points on given line = (-12,-2) and (0,-4) because you can see them on the graph.  Then draw a parallel line thru (0,6)

To get from (0,-4) to (0,6) your x stays constant and your y coordinate increased by 10.  So your new point will do the same in relation to (-12,-2)  the x will stay constant at -12 and your y will increase by 10 to +8.  

So the answer is A (-12,8)

You can check this because parallel lines have the same slope so

y2-y1/x2-x1 should be equal for both lines.

Line 1:  -4 - (-2) / 0 - (-12) = -2/12 = -1/6

Line 2:  6 - 8 / 0 - (-12) = -2/12 = -1/6

What is the slope of a line perpendicular to the line whose equation is 5x+6y=425x+6y=42. Fully reduce your answer.
Vlada [557]

Answer:  m= 1/420

Step-by-step explanation:

5x + 6y - 6y - 425x = 42

5x -425x = 42

0 = -420x - 42

m = -420

slope of a perpendicular line = 1/420

if that helps.

Can someone help me do this
djyliett [7]

Answer:

See below

Step-by-step explanation:

It's hard to see your photo but if that say m∠T than your answer would be

m∠ L.

The drawings are saying the the triangles are congruent which means all the interior angles of one triangle are congruent to the angles of the second triangle.    m∠M = m∠J,   m∠K = m∠E and m∠L = m∠T

Since you have two of the angles, you can also determine what m∠L and m∠T is equal to.  The sum on all interior angles must be 180 degrees.

180 - 86 - 32 = 62
