Last week at a festival, a man sold 4 times as many tie-dyed T-shirts as silk screened shirts. He sold 180 shirts altogether. Ho

Let the number of tie-dyed T-shirts = x

The man sold 4 times as many tie-dyed T-shirts as silk-screened shirts.

So, the number of silk-screened shirts = 4x

He sold 180 shirts altogether

So,

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

So, the number of tie-dyed shirts = 36

What is the answer of this question plzzzzzzzzzzz say fast

Answer:

$1=3=70^{0} \\2=4=5=110^{0}$

Step-by-step explanation:

Given angle is 110°

Now,

$4=2\,\,and\,\,4=5\,\,;[vertical\,\,angle\,\,and\,\,corresponding\,\,angle\,\,respectively ]$

From the figure,

$4=110^{0}\,\,;[alternate\,\,angle]$

$So,\,\,2=5=110^{0}$

And, as 1,2,3,4 are vertical angles and 2 = 4 = 110°

1 = 3 = 180° - 110° = 70°

Hope you have understood this.....

ask me if you have any confusion.....

if you liked it pls mark it as the brainliest
