We have that The midpoint M of the line segment joining the points

S = (-4,-2)
T = (6, -8)

$M=(-3,-1)$

From the question we are told

Find the midpoint M of the line segment joining the points

S = (-4,-2)
T = (6, -8

Generally the equation for the midpoint is is mathematically given as

$M=\sqrt{\frac{x1+x2}{2},(y1+y2)^2}\\\\M=\frac{-4+-2}{2},\frac{(6+-8)}{2}}$

$M=(-3,-1)$

Therefore

The midpoint M of the line segment joining the points

S = (-4,-2)
T = (6, -8)

$M=(-3,-1)$

Area=legnth times width
42=legnth times width

Answer:

Using the Angle Addition Postulate, 20 + m∠DBC = 80. So, m∠DBC = 60° using the subtraction property of equality.

Step-by-step explanation:

If point D is the interior of angle ABC, then the angle addition postulate theory states that the sum of angle ABD and angle DBC is equals to angle ABC. The angle addition postulate is used to measure the resulting angle from two angles placed side by side.

From the attached image, ∠ABD and ∠DBC are placed side by side to form ∠ABC. Given that m∠ABD = 20° and m∠ABC = 80°

Hence, using angle addition postulate:

m∠ABD + m∠DBC = m∠ABC

20 + m∠DBC = 80

subtracting 20 from both sides (subtraction property of equality)

m∠DBC = 80 - 20

m∠DBC = 60°

Simplify sin^2y/sec^2 y−1 to a single trigonometric function

liubo4ka [24]

Answer:

$\frac{ { \sin}^{2} y}{ { \sec}^{2}y - 1 } = { \cos }^{2} y$

Step-by-step explanation:

We know that ${ \tan }^{2} y = { \sec }^{2} y - 1$

Also , ${ \tan}^{2} y = \frac{ { \sin }^{2} y}{ { \cos }^{2}y }$

So ,

$\frac{ { \sin }^{2}y }{ { \sec }^{2}y - 1 } = \frac{ { \sin}^{2} y}{ { \tan }^{2} y} = \frac{ { \sin }^{2}y }{ \frac{ { \sin}^{2} y}{ { \cos}^{2}y } } = { \cos }^{2} y$
