Answer:Answer is D (3,1/2)
Step-by-step explanation:
It was right on edg.
Answer:
the second choice is correct
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 
x - 9 is in this form
with slope m =
• Parallel lines have equal slopes, hence
y = x + c ← is the partial equation of the parallel line
To find c substitute (- 8, - 18) into the partial equation
- 18 = - 6 + c ⇒ c = - 18 + 6 = - 12
y = x - 12 ← equation of parallel line
The triangles are similar so ∆JKL is just an enlargement of ∆WVU. Therefore the ratios of the side lengths are the same. 10:20 = 1:2 so the side lengths for ∆JKL must be in the ratio 1:2. 15 × 2 = 6x so 30 = 6x so x = 5

Step-by-step explanation:
Answer:
44°
Step-by-step explanation:
Given:
m<DOC in circle O = 44°
m<COB in circle O = 80°
Required:
Measure of arc DC.
SOLUTION:
<DOC is a central angle that intercepts arc DC. Central angles are said to be congruent to the arc they intercept.
Therefore, m<DOC = measure of arc DC.
Since m<DOC = 44°, the measure of arc DC = 44°.
Arc DC = 44°
