Answer:
m = -4.33333 or -4 and 1/3
Step-by-step explanation:
gradient = (difference in y)/(difference in X)
m = (-1-12)/(8-5)
m = -13/3
m = -4.3333333
Sum of angles of a triangle = 180
a+b+c=180
a + (5a) + (4a-13) = 180
Simplify and solve for a:
10a-13=180
10a=193
a=19.3
b=5*19.3=96.5
c=4*19.3-13=77.2-13=64.2
Check: a+b+c=19.3+96.5+64.2=180 ok.
Answer: B Exactly one solution
Step-by-step explanation:
5x+8-7x=-4x+1
-2x+8=-4x+1
-2x+4x=-7
2x=-7
x=-7/2
The measure of the angle formed by 2 chords that intersect inside the circle is 1/2 the sum of the chords' intercepted arcs.
m∠RST = (143+33)/2 = 176/2 = 88°
Answer:
x
Step-by-step explanation:
It still would be a negative.
