Answer:
m(arc)ED = 39 degrees
Step-by-step explanation:
The measure of an arc of a circle is equal to the measure of the central angle that intercepts it.
BE is a diameter. That means that m<BPE = 180.
AC is a diameter. That means that m<APC = 180.
Let's start with angle BPE to find w:
m<BPE = m<BPA + m<EPA = 180
4w + 8 + 4w + 4 = 180
8w + 12 = 180
8w = 168
w = 21
Now we deal with angle APC:
m<APC = m<APE + m<EPD + m<DPC = 180
4w + 4 + m<EPD + 2w + 11 = 180
6w + 15 + m<EPD = 180
m<EPD + 6w = 165 Equation 1
Now we use w = 21 in Equation 1.
m<EPD + 6w = 165
m<EPD + 6(21) = 165
m<EPD + 126 = 165
m<EPD = 39
Since the arc measure equals the measure of the central angle that intersects it, m(arc)ED = 39 degrees
Answer: m(arc)ED = 39 degrees
Answer:
C. 20 feet
Step-by-step explanation:
The question has given you tan∅ = 20/50. You know that tan is opposite over adjacent. So if the opposite end is 20, that means the tree is 20 feet tall and the girl is <em>50 feet away</em>.
Divide 132 with 12
132/12 = 11
11 trays are needed to make 132 biscuits
hope this helps
Answer:
P40000 at 5%
P20000 at 4.5%
I am curious as to what the P stands for. Can you tell me?
Step-by-step explanation:
Let x = amt. invested at 5%
y = amt. invested at 4.5%
(1) x + y = 60000 (2) .05x + .045y = 2900
50x + 45y = 2900000
-45 times (1) <u>-45x - 45y = -2700000 </u>
5x = 200000
x = 40000
40000 + y = 60000
y = 20000
