Answer:
Step-by-step explanation:
Draw a line from S to T'
T' is where the angle PTQ intersects the circle when SR is extended so that it hits the circumference of the circle.
This line bisects the 50 degree angle (which is given. It also bisects PRS.
y is shown on the diagram.
Your first job is to find y
It's y + 90 + 25 = 180 because all triangles are made up of 180 degrees.
y it turns out is 65 degrees.
Now comes the interesting part. PRT' is supplementary to y. It is labeled as 180 - y
<PRT' + Y = 180
y = 65
<PRT' = 180 - 65 = 115
Since PRT' = 115 and since PR = PT' (They are both radii). x/2 + x/2+ 115 = 180 I'll talk about x/2 down below this.
x + 115 = 180 All triangles = 180
x = 65.
Where did x/2 come? As long as PTQ is situated on the arc that it is on then <PTQ is always going to be x. You will have to piece together the two diagrams to make this work.i
It's a very good application of circles and lines well worth your time to get to know.

Answer:
Step-by-step explanation:
3x-7 ≤ 14
3x≤ 14+7
3x≤ 21
x≤ 21/3 = 7
=> x = (-∞;7]
That means that x can be any negative number and any positivi number (1,2,3...7)
Y < 2x + 4.....u have a dashed line with shading below the line....u have a y int of (0,4)...u have an x int of (-2,0) and a slope of 2
y > -x - 3...u have a dashed line with shading above the line....u have a y int of (0,-3) and an x int of (-3,0) and a slope of -1
ur graph is : There is a problem....it will either be the 2nd one or the 3rd one....because one of ur inequalities is written incorrectly...
** IF y > -x - 3 is supposed to have an equal sign in there...then ur answer is the 2nd graph
** IF y < 2x + 4 is supposed to have an equal sign in there...then ur answer is the 3rd graph
