19. Two angles are supplementary. The measure of one angle is four times the measure of the other angle. Find the measure of eac
Marysya12 [62]

36 and 144

Explanation

Two Angles are Supplementary when they add up to 180 degrees

Step 1

Let

x= angle 1

y= angle2

The measure of one angle is four times the measure of the other angle,then

\begin{gathered} \text{angle}1=4\cdot\text{angle}2\text{    } \\ x=4y\text{   Equation(1)} \end{gathered}

x and y are supplementary angles , then

x+y=180\text{   Equation (2)}

Step 2

use Equation (1) and (2) to find x and y

\begin{gathered} x=4y \\ x+y=180 \end{gathered}

replace Equation (1) in Equation (2)

\begin{gathered} 4y+y=180 \\ 5y=180 \\ y=\frac{180}{5} \\ y=36 \end{gathered}

replace the value of y= 36 in equation (1) to find x

\begin{gathered} x=4y \\ x=4\cdot36 \\ x=144 \end{gathered}

Hence, the answer is 36 and 144

Complete the equivalent ratio diagram to find cheese stick
diamong [38]

Answer:

The blank on the top is 0.31 because that is what you multiply 80 by

The blank in the middle is 24.8 because that's what you get when you multiply 80 by 0.31

The blank on the bottom is 0.31 because that is what you multiply 80 by

Step-by-step explanation:

Use proportions to solve

80/100 = x / 31

80*31 = 100x

2480 = 100x

x = 24.8

From a point P outside line segment AB =6cm, construct a line PQ parallel to line segment AB.​
goldfiish [28.3K]

Answer:

We drawn the graph.

Step-by-step explanation:

We have a line segment AB = 6cm and a point P outside that a line segment.  

We want to construct a line PQ that is parallel to  line segment AB.

If PQ is parallel to longer AB, this means that a line PQ is equidistant from  line segment AB everywhere.  

We use the geogebra.org site to draw it.

We drawn the graph.
