Answer:
m∠1 = 50°, m∠2 = 90°, m∠3 = 40°, and m∠4 = 50°
Step-by-step explanation:
Angles on straight line are equal;
Vertical angles are equal,
Complementary angles add up to 90°.
Angles on straight line adds up to 180°
True false false true divided 4626÷340=13.605882353
<span>A) y=-2x+19
B) y=x+7
Multiplying B) by -1
B) -y = -x -7 then adding it to A)
A) y = -2x + 19
3x = 12
x = 4
y = 11

Answer:
Step-by-step explanation:
Let
x ----> the average depth of the resulting layers of ash and rock
we know that
To find out the average depth, divide the cubic kilometers of molten rock by the area where all the ejected material fell.
so
Convert to meters
Remember that
so
Convert to mixed number
