Answer:

<em>mDBC = 341 °</em>

Step-by-step explanation:

Arc DBC is almost the whole circle, if you were to exclude the degree measure of minor arc DC; which is, in other words m∠ DPC

Now by Vertical Angles Theorem:

m ∠ DPC = m∠ APB, ⇒ provided BD, and AC are diameters

m∠ DPC = 19°

This would mean ⇒

mDBC = 360 - m∠ DPC,

mDBC = 360 - 19,

mDBC = 341 degrees ( ° )

3x + 5y = 7<br> 4x + 3y = 2<br><br> Both x and y have to be the same numbers!
Black_prince [1.1K]
Simultaneous Equations:
(3x + 5y = 7)×(-3)
(4x + 3y = 2)×(5)

-9x - 15y = -21
20x+15y =10        (-15y and and+15y cancels out)

11x = -11
\frac{11x}{11} = \frac{-11}{11} (11 and 11 cancels out)
x= -1
substitute the x we found into either original expressions

3(-1) + 5y = 7
-3 + 5y = 7
+3 -3+ 5y = 7+ 3
5y = 10
\frac{5y}{5}=\frac{10}{5} (5 and 5 cancels out)
y=2 
Check it!
4(-1)+3(2) = 2
-4 + 6 = 2
2 = 2

3(-1) + 5(2) = 7
-3 + 10 = 7
7 = 7

x= -1
y= 2

fgiga [73]

So here's what we have so far:

2 mm: 8 m

We can factor out a 2:

1 mm: 4 m

 

If you want, we can go further by converting into the same unit. A little unorthodox, but just to show how to do it:

1 meter = 1000 millimeters

4 * 1000 = 4000

1 mm: 4000 mm
