Answer:
Using the Angle Addition Postulate, 15 + 40 = m∠ABC. So, m∠ABC = 55° after simplifying.
Step-by-step explanation:
The Angle Addition Postulate is gotten from angles placed side by side to form a resulting angle that is the sum of all the individual angles.
If D is the interior of ABC then, ABC is split into two parts i.e ABD and DBC, then the measure of ABC is the sum of the individual two parts
m∠ABC = m∠ABD + m∠DBC.
Using the Angle Addition Postulate:
m∠ABC = m∠ABD + m∠DBC
m∠ABC = 15 + 40 = 55°
m∠ABC = 55°
So, plug in what you're given and solve
x is -2
(3x) * 9
(3 (-2)) * 9
-6 * 9
-54
then
27(-2)
-54
For the first it's the same
for the second
x is 0
(3x) * 9
(3 (0)) * 9
0 * 9
0
27x
27(0)
0
For the second it's the same
x is 4
(3x) * 9
(3(4)) * 9
12 * 9
108
27x
27(4)
108
The given expressions are equivalent. This was proved in the diagram.
Hope this helps :)
Answer:
24 in long by 12 in wide.
Step-by-step explanation:
l=2w
288=(2w)×w
288=2w^2
144=w^2
12=w
width is 12 inches. Plug that in to find length...
l=2×12
l=24
Answer:
14.45*10^6
Step-by-step explanation:
(1.7*10^4)*(8.5*10^2)=14.45*10^6
