Answer:

B. $67^{o}$

Step-by-step explanation:

We have been given image of an circle. We are asked to find the measure of angle PTS.

Upon looking at our given circle, we can see that angle PTS is formed inside circle by intersection of secant PQ and RS, so the measure of angle PTS will be half the sum of arc PS and QR (Intersecting Secants Theorem).

$m\angle PTS=\frac{\widehat{PS}+\widehat{QR}}{2}$

$m\angle PTS=\frac{60^{o}+74^{o}}{2}$

$m\angle PTS=\frac{134^{o}}{2}$

$m\angle PTS=67^{o}$

Therefore, the measure of angle PTS is 67 degrees and option B is the correct choice.

nignag [31]

Answer:

Step-by-step explanation:

The two base angles cannot both be 92 degrees because they would add up to 184 which is more degrees than any triangle has. The apex angle (the top angle) therefore has 92 degrees.

The base angles are equal and found as follows.

2*b + 92 = 180 Subtract 92 from both sides

2b +92-92 = 180-92

2b = 88 divide by 2

2b/2=88/2

b = 44

The only angle measurement that fits is 44

Further mathematics: Find the derivative of the function x^2 y + (xy)^3 +3x=0 at (-1 , 3)

vesna_86 [32]

Answer:

Step-by-step explanation:

Implicit differentiation:

x^2 y + (xy)^3 + 3x = 0

x^2 y + x^3y^3 + 3x = 0

Using the product rule:

2x* y + x^2*dy/dx + 3x^2 y^3 + x^3* (d(y^3)/dx) + 3 = 0

2xy + x^2 dy/dx + 3x^2 y^3 + x^3* 3y^2 dy/dx + 3 = 0

dy/dx(x^2 + 3y^2x^3) = (-2xy - 3x^2y^3 - 3)

dy/dx= (-2xy - 3x^2y^3 - 3) / (x^2 + 3y^2x^3)

At the point (-1, 3).

the derivative = (6 - 81 - 3)/(1 -27)

= -78/-26

= 3.
