Answer:
m∠C=30°
Step-by-step explanation:
we know that
<u>Vertical Angles</u> are the angles opposite each other when two lines cross. They are always equal
so
m∠C=m∠D
substitute the given values
![(x+5)\°=(-2x+80)\°](https://tex.z-dn.net/?f=%28x%2B5%29%5C%C2%B0%3D%28-2x%2B80%29%5C%C2%B0)
Solve for x
![x+2x=80-5\\3x=75\\x=25](https://tex.z-dn.net/?f=x%2B2x%3D80-5%5C%5C3x%3D75%5C%5Cx%3D25)
<em>Find the measure of angle C</em>
m∠C=(x+5)°
substitute the value of x
m∠C=(25+5)=30°
Answer:
1+2+27=30
3+6+21=30
20+3+7=30
So many more, but here are a few.
Answer:
A. 189 ft³
Step-by-step explanation:
If the volume of the original prism is ...
V = LWH
then the volume of the smaller one will be ...
v = (L/2)(W/2)(H/2) = LWH/8 = V/8
The smaller prism will have a volume of ...
1512 ft³/8 = 189 ft³
_____
As you can see from the above, the scale factor for volume is the cube of the scale factor for the linear dimensions: (1/2)³ = 1/8.
Using it's concept, it is found that the coefficient of the mathematical expression 7m² + 2(19) is of 7.
<h3>What is the leading coefficient of a polynomial?</h3>
The leading coefficient of a polynomial is the <u>term that multiplies the highest exponent</u>.
In this problem, the expression is given by:
7m² + 19.
The highest exponent is of 2, in m², hence the leading coefficient is of 7.
