Angle 1 and angle 2 are a linear pair. m of angle 1=x-35 and m of angle 2 =x+83. find the measure if each angle

Angle 1 = 31 degree

Angle 2 = 149 degree

Step-by-step explanation:

We have given that :

M of Angle 1 = x-35 and m of Angle 2 = x+83

Angle 1 and Angle 2 are linear pair

linear pair means the sum of angle is 180  

⇒ Angle 1+ Angle 2 = 180

⇒ x-35 + x+83 = 180

⇒ 2x+48 =180

⇒ 2x= 132

⇒ x= 66

Now put the values of x in both the angle

Angle 1 = x-35 = 66-35 = 31 degree

Angle 2 = x+83 = 66+83 = 149 degree

i dont know men

step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
