Please answer this question, 30 points and will give brainliest!
kotykmax [81]

Answer:

∠C = 80 ° ; ∠ T = 40°.

Step-by-step explanation:

Triangle CRS is isosceles because it has two sides of equal length. (CR and CS are radii).

An isosceles triangle has also two equal angles, which means that ∠CRS= ∠CSR.

Therefore, ∠C = 80 ° (180° – 50° - 50°)  because the sum of angles in a triangle is 180 degrees.  

∠C is the central angle of the arc RS.

∠ T is the inscribed angle of the arc RS.

An inscribed angle is half of a central angle that subtends the same arc on the circle, so the inscribed angle ∠ T is half of the central angle ∠C. Since ∠C = 80 °, we can easily determine the measure of ∠ T:  

80° divided by 2 is 40°.

Find the slope of the line through each pair (1,-19),(-2,-7)
expeople1 [14]

hello i see that no one has answered your question yet well im here to help:)

(1,-19),(-2,-7)

so here one way you can find the slope

i usually always use this to help me to keep it in order

------------------

(X1,Y1)(X2,Y2)

   X2-X1

   Y2-Y1

use this and your garanteed to get the right answer everytime

------------------

X = -2 – 1 = -3

Y = -7 – -19 = 12

once you do that you divide if possible

12/-3

which gives you -4

so your answer is -4

its really not hard you just got to get use to it

hope it help you:)
