PQ is bisected by RS at R. It means that PRQ is a line segment with PR = RQ and each of half of PQ.
RQ = PQ/2 = 1/2 [ 4 3/4 ] = 1/2 * 19/4 = <em>19/8 </em> = 2 3/4
Answer:
The formula for the vertex of the parabola is -b/a. Plugging this in we get -(-4)/1 or 4.
Answer:
B) ∠z = 40°
Step-by-step explanation:
<u>All three angles of a triangle add up to 180°</u>. In this image, you can see that the angle ∠ACD is 130°. Because ∠ACB and ∠ACD are supplementary angles it means that their angles equal 180° when added together.
If ∠ADC = 130° then:
180° - 130° = 50°
Since we now know that ∠ACB is 50°, we can subtract our two angles from 180° to get the measurement for angle z.
180° - 50° - 90° =
180° - 140° = 40°
