Since k and j are parallel, angle 4 is equal to the angle to the left of 60 degrees. Since j is a line, the angle to the left of 60 added on to 60 is 180.

180 -60 = 120. The angle is 120 degrees.

Since angle 4 is equal to that angle, angle 4 is also 120 degrees.

Hope this helps

Answer:

20%

Step-by-step explanation:

Step 1: Subtract starting value minus the final value (decrease)

\$5.75 - \$4.60\\\\= 5.75 - 4.60 \\\\= 1.15

Step 2: Divide the decrease by the original number

1.15 \div 5.75\\\\= \frac{1.15}{5.75}\\\\= 0.2

Step 3: Multiply the result by 100 to get a percent decrease

0.2 \times 100\\\\= 20

Therefore, the percent decrease of the price of paper per package is 20%

<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>

\qquad \qquad\huge \underline{\boxed{\sf Answer}}

<h3><u>Distance travelled each day is</u> : </h3>

  • 32.6 km

<h3><u>Explanation</u> : </h3>

Distance travelled in 14 days is : 456.4 km

And if he travels same Distance each day, so let the Distance travelled on each day be x

According to question ~

\qquad \sf  \dashrightarrow \: 14 \times x = 456.4

\qquad \sf  \dashrightarrow \: x = 456.4 \div 14

\qquad \sf  \dashrightarrow x = \: 32.6  \: \: km

So, he travels 32.6 km per day

A balloon has a circumference of 23 cm. Use the circumference to approximate the surface area of the balloon to the nearest squa
AveGali [126]
To get the surface area of a sphere, we need to have the radius. We are given the circumference. The circumference formula is C=2πr.  We need to solve for r. 
23 = 2πr
r=3.66

The calculation for surface area is <span>A = 4πr^2. 
</span>A = 4<span>π(3.66)^2

Solve for A.

A= 168 cm^2.</span>
