Given:SW is diameter of circleR
m\overarc ST = 30\degree
Prove: RTW = 15\degree
Answers
Check the picture below.
we know that the arcST is 30°, meaning the inscribed angle intercepting it will be half that or 15°.
in the triangle RWT, two sides of it are RT and RW, both of which are radius segments and thus equal, meaning that triangle RWT is an isosceles, and in an isosceles the twin sides also make twin angles, meaning that ∡RTW is a twin of the inscribed angle ∡RWT.

3х - 4y = 15
7x+y= 4
Substitution
Answers
Answer:
3x-4y=15
7x+y=4
Solve7x+y=4 for y:
7x+y=4
7x+y+−7x=4+−7x (Add -7x to both sides)
y=−7x+4
Step: Substitute −7x+4 for y in 3x−4y=15:
3x−4y=15
3x−4(−7x+4)=15
31x−16=15 (Simplify both sides of the equation)
31x−16+16=15+16 (Add 16 to both sides)
31x=31
(Divide both sides by 31)
x=1
Step: Substitute 1 for x in y=−7x+4:
y=−7x+4
y=(−7)(1)+4
y=−3(Simplify both sides of the equation)
Answer: x=1 and y=−3

Answer:
the 4th answer : a = 3 and b = sqrt(3)
Step-by-step explanation:
remember that i = sqrt(-1).
so, when you "take out" -1 of -3, you get 3.
sqrt(-3) = sqrt(3×-1) = sqrt(3)×sqrt(-1) = sqrt(3)i

Step-by-step explanation:
x +y = y-m
subtract y on both sides which will cancel them out, we are left with
x = -m
multiply both sides by -1 to get rid of the -m
x × -1 = -x, -m × -1 = m

14b.) RS = 60; ST = 36; RT = 96
Step-by-step explanation:
Since you have correctly solved for y = 7, all you need to do for b is to plug in y.
RS = 8(7) + 4 = 60
ST = 4(7) + 8 = 46
(You can add RS and ST or plug in for y for RT)
RT = 15(7) - 9 = 96
