2x + 1.5x +20 = 90 
3.5 x = 90-20 
3.5 x = 70 
x = 70/3.5 
x = 20 
angle DAE = 2*20 = 40 
angle CAD = 1.5*20 +20 = 50

AleksandrR [38]

Answer:

Image result for The length of a rectangle is 3 more than five times its width. If the perimeter of the rectangle is 30 meters, find the dimensions of the rectangle.

To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.

Find rhe volume of a cylinder with a diameter of 10 inches and a height of 20 inches
IrinaK [193]
Since the diameter of the cylinder is 10, its radius is half that, or 5, thus

\bf \textit{volume of a cylinder}\\\\
V=\pi r^2 h~~
\begin{cases}
r=radius\\
h=height\\
-----\\
r=5\\
h=20
\end{cases}\implies V=\pi (5)^2(20)

Compare and contrast expanding and simplifying algebraic expressions with simplifying numeric expressions. For example, compare
larisa [96]
<span>With algebraic expressions, you can’t add and subtract any terms like you can add and subtract numbers. Terms must be like terms in order to combine them. So, you can’t always simplify an algebraic expression by following the order of operations. You have to use the distributive property to rewrite the expression and then combine like terms to simplify. With numeric expressions, you can either simplify inside the parentheses first or use the distributive property first.</span>

\implies\huge{\red{ x={17\sqrt 3}}}

\sin 30\degree=\frac{17}{y}

\implies\frac{1}{2}=\frac{17}{y}

\implies\huge{\purple{ y={34}}}
