Answer: angle Q = 75 degrees
--------------------------------------------
The tickmarks on segments PR and PQ indicate they are congruent, ie PR = PQ. Because of this, the base angles R and Q (opposite the segments mentioned) are congruent
Angle R = Angle Q
Since angle R is (2x+15) degrees, so is angle Q
Now use the idea that adding three angles of a triangle leads to 180 degrees
P+Q+R = 180
x+(2x+15)+(2x+15) = 180
5x+30 = 180
5x = 180-30
5x = 150
x = 150/5
x = 30
If x = 30, then angle Q is
angle Q = (2x+15) degrees
angle Q = (2*x+15) degrees
angle Q = (2*30+15) degrees
angle Q = (60+15) degrees
angle Q = 75 degrees
Answer: i believe it is 57
Step-by-step explanation:
You seem to want a ratio.
If that's the case:
18 in 1 ft
------- * --------- = 3/8 = 0.375
4 ft 12 in
Answer:
Option B
Step-by-step explanation:
Given equation gives the information about the temperature in Vancouver over a period of 4 hours.
y = -2x + 43
Here 43 represents the initial temperature and (-2) represents the temperature fall in every one hour.
x = duration or time
Therefore, equation states that initial temperature when measured was 43 °F and it is dropping by 2 degrees per hour.
Option B is the answer.
