Answer:
Answer:
28+66+86=180
180=180
Step-by-step explanation:
Since there is a triangle and the 3 measures from the angles we can find the value of x using the hint given that the sum of the interior angles must be 180°
Write the equation
\begin{gathered}x+(2x+10)+(3x+2)=180\\\end{gathered}
x+(2x+10)+(3x+2)=180
Simplify left side of the equation
\begin{gathered}6x+12=180\\\end{gathered}
6x+12=180
Solve equation for x
\begin{gathered}6x=180-12\\6x=168\\x=28\end{gathered}
6x=180−12
6x=168
x=28
Replace x into the 3 angles and find their respectives values
\begin{gathered}A=x\\A=28\\\\B=2x+10\\B=2*28+10\\B=56+10\\B=66\\\\C=3x+2\\C=84+2\\C=86\end{gathered}
A=x
A=28
B=2x+10
B=2∗28+10
B=56+10
B=66
C=3x+2
C=84+2
C=86
Check if the answers are correct
\begin{gathered}28+66+86=180\\180=180\end{gathered}
28+66+86=180
180=180

Answer:
Step-by-step explanation:
according to the midsegment theorem, a midsegment of a triangle is parallel to a side of a triangle and its length is 1/2 length of the side.
1/2FG= 15, SO FG=30,
1/2 GH=36 SO GH=72
AREA = 1/2(72*30)=1080 CM^2
Answer: True
The ratio is equivalent to
1 kg = 1000 g
Answer:
7b^3 + 9b^2 + 8b
Step-by-step explanation:
Combine like terms
My teacher taught me a few years ago to put like terms in the same format so they're easier to combine:
b^3 + <em>7b </em>+ <u>9b^2</u> + <em>b </em>+ 6b^3
Here I have all terms to the 3rd power bolded, all terms to the 2nd power underlined, and all terms to the 1st power italicized. That makes it easier to combine those that are similar
b^3+ 6b^3 = 7b^3
<u>9b^2</u> - remains the same
<em>7b </em>+ <em>b = 8b</em>
Now just reorder them to where the exponents are listed from greatest to least:
7b^3 + 9b^2 + 8b
