Answer:
108º
Step-by-step explanation:
to find the sum of interior angles: ( n − 2 ) × 180 = x
x = 540º
n = # of interior angles
first, solve for n
(n - 2) • 180 = 540 distribute to 180 to (n - 2)
180n - 360 = 540 add 360 to both sides
180n = 900 divide both sides by 180
n = 5
to find measure of each angle:
540 ÷ 5 = 108º
Answer:
$372.330
Step-by-step explanation:
if 1 mile = $0.45 and you want to find out 827.4 miles
you should multiple $0.45 × 872.4
1 mile : $0.45
827.4 × $0.45 = 372330
827.4 : $372.330
Answer:
Area=Base length x Height
Area= O x g.
Answer:
Step-by-step explanation:
Given:
Solving for 
:
Both are
indicators of the chemical composition of silicate minerals, magmas and rocks.
Mafic is
used for silicate minerals, magmas and rocks that are composed of heavier
elements, like magnesium, iron, calcium and sodium. They are dark and have high
specific gravities.
<span>Opposite to
the this, felsic silicate minerals, magmas and rocks in their composition have
less from these heavy elements. They are composed from silicon, oxygen,
aluminium and potassium, are light in color and have lower specific gravities.</span>
