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)
Answer:
x = 18√3
Step-by-step explanation:
From the picture attached,
In a right triangle,
Measure of one angle = 30°
Measure of adjacent side of the angle = 9 units
We have to find the measure of Hypotenuse from the given properties.
By cosine rule,
cos(30°) = 


Therefore, measure of Hypotenuse is 18√3 units.
Answer:
(0, 3)
Step-by-step explanation:
1. Find the slope:

2. Calculate the y-intercept using a given point:
(-8, -3)
-3 =
+ b
-3 = -6 + b
-3+6 = -6+6 + b
3 = b
3. Write in slope intercept form:

Therefore, the y-intercept is 3.
The graph for this table is shown below.
hope this helps :)
