0.85 is the decimal equivalent of 17/20.
Answer:
b. DAC≅DBC
Step-by-step explanation:
∠DCB≅∠DCA=90° as they are right angles at the perpendicular lines
DC=DC reflexive property(they are the same line)
AC=CB they are both the radius of the same circle
DAC≅DBC due to SAS(Side angle Side)
This is something to memorize
y = r*sin(theta)
so if y = 2, then
2 = r*sin(theta)
Divide both sides by sin(theta) to get
r = 2/sin(theta)
r = 2csc(theta)
Answer:
y - y1 = m(x - x1)
Step-by-step explanation:
The point slope form equation is [ y - y1 = m(x - x1) ]
(x1, y1) is any given point on the line.
m is the slope.
To solve this you would need these things:
- Slope (y2-y1/x2-x1)
- Y-intercept (y = mx + b)
Best of Luck!
