Since a square has a complementary angle, it’s four angle in total is 360 degrees. But the angle b is given in the question and says what angle it was. So, angle b is 4x+10. What do we do about these numbers? We just created them into an equation and solve them algebraically. The way to solve it is this way:
4(4x+10) = 360
16x +40 = 360
16x= 320
X= 20

The answer is x= 20

4(4x+10)=360

16x+40=360
-40 -40

16x=320
÷16 <span> ÷16

x=20

X2 - 16, is the answer. The first one.

Answer: Hence, our required probability is $\dfrac{1}{386206920}$

Step-by-step explanation:

Since we have given that

Numbers in a lottery = 60

Numbers to win the jackpot = 7 numbers

We need to find the probability to hit the jackpot:

So, our required probability is given by

$P=\dfrac{^7C_7}{^{60}C_7}\\\\P=\dfrac{1}{386206920}$

This is a combination problem as we need to select 7 numbers irrespective of any arrangements.

Hence, our required probability is [tex]\dfrac{1}{386206920}[/tex
