In equilateral triangle RST, R has coordinates (0, 0) and T has coordinates of (2a, 0). Find the coordinates of S in terms of a.
2 answers:
The x coordinate of S will be 1/2 * 2a = a.
and since the half triangle is 30-60-90 the y coordinate will be sqrt3 a
so S is (a , sqrt3a)
Answer:
The S coordinate :
Step-by-step explanation:
In equilateral triangle RST, R has coordinates (0, 0) and T has coordinates of (2a, 0)
We need to find the third coordinate of triangle RST.
R(0,0)
T(2a,0)
S(x,y)
RT=RS=ST (because RST is an equilateral triangle)
Using distance formula,
Hence, The S coordinate :

When a quadrilateral is inscribed in a circle, the sum of opposite angles is 180 degrees.
A+C=180
95+C=180
C=180-95
C=85
Therefore the answer is B). I hope this helped.

Answer is
Point-slope form: y + 1 = 4(x -1)
Assuming you wanted
Slope-intercept form: y = 4x -5
Step by step
y - - 1 = 4(x -1)
y + 1 = 4(x -1)
y + 1 = 4x -4
y = 4x -5
