We have that
<span>1) What is the measure in degrees of ∠ 1?
</span>∠ 1+110=180----> ∠ 1=180-110---> ∠ 1=70°---> angles 1 and 110 are supplementary angles
<span>2) What is the measure in degrees of ∠ 2?
</span>∠ 2+115=180----> ∠ 2=180-115----> ∠ 2=65°---> angles 2 and 115 are supplementary angles
<span>3) What is the measure in degrees of ∠ 3?
</span>∠ 3=∠ 2----> ∠ 3=65°------> angles 3 and 2 are congruent by corresponding angles
<span>4) What is the measure in degrees of ∠ 4?
</span>∠ 4=115---> ∠ 4=115°----> angles 4 and 115 are congruent by corresponding angles
<span>5) What is the measure in degrees of ∠ 6?
step 1
find the value of angle </span>∠7
<span>we know that
</span>∠1 +∠2 +∠7=180---------> (sum of the internal angles of a triangle
∠7=180-(∠1 +∠2)------> ∠7=180-(70+65)----------> ∠7=45°
∠6=∠7----------> ∠6=45°--------------> <span> angles </span>6<span> and </span>7<span> are opposed by the vertex, so they are congruent.</span><span>

<span>She used the associative property which should only be used with positive numbers..</span>
I think its C Because Aob is a given angle Boc is where we prove Aob so Im 95% sure its c
Answer:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes
Step-by-step explanation:
If the half-life is t, then every t days, the amount of the radioactive isotope will be cut in half.
(1/2)^(number of half-lives) = 3%
number of half-lives = ln(0.03) / ln(0.5)
This gives the number of half-lives as 5.06.
Then 300 days = (5.06)(length of 1 half-life)
length of 1 half-life = 300 / 5.06 = 59.29 days
