It has a right angle (90 degrees) and 2 sides are equal which makes it isosceles.
So there's only one choice left.
Answer:
The measure of angle DPA is 39°
Step-by-step explanation:
step 1
Find the value of x we know that arc AB+arc BC+arc CD+arc DA=360°
substitute the values
(5x+10)°+(x+1)°+3x°+(3x+25)°=360°
Solve for x
(12x+36)°=360°
12x=360°-36°
x=324°/12=27°
step 2 Find the measure of angle DPA
we know that The measurement of the external angle is the semi-difference of the arcs which comprises
m∠DPA=(1/2)[arc DA-arc BC]
arc DA=3(27)+25=106°
arc BC=27+1=28°
substitute the values
m∠DPA=(1/2)[106°-28°]=39°
Let h = amount of hours
Since they earn $7.50 per hour, we can multiply that by an unknown amount of hours to get $116.25. Let's solve:
Divide both sides by 7.5 to isolate the h, amount of hours.
Simplify.
In conclusion, someone would have to work 15.5 hours to earn $116.25 if they earn $7.50 per hour.
0.4 has 4 tenths
Look at 0.4 as 0.40
Divide the 40 by 10 and get 4
-Hope this helped!
The answer should be B, in other words 41
