Answer:
102 deg
Step-by-step explanation:
The sum of the interior angles of a n-gon
are equal to ( n-2)*180
for a pentagon ( 5-2)(180) = 540
88+118+132+100 + x = 540 x= 102 deg
Answer:
x = -1 and y = -1
Step-by-step explanation:
to solve this equation we say
let
2x-5y=3.......................................... equation 1
4y-x=-3............................................equation 2
from equation 2
4y-x=-3............................................equation 2
4y + 3 = x
i.e
x = 4y + 3 ............................................. equation 3
put x = 4y + 3 in equation 1
2(4y +3) - 5y = 3
8y + 6 -5y = 3
3y +6 = 3
3y= 3-6
3y -3
divide both sides by the coefficient of y which is 3
3y/3 = -3/3
y = -1
put y = -1 into equation 3
x = 4y + 3 ............................................. equation 3
x = 4(-1) + 3
x = -4 + 3
x = -1
therefore the value of x = -1 and y = -1 respectively
Step-by-step explanation:
Equation 1

Equation 2

1 and 3 is the answer I guess
Answer:
2=5
4=6
6=7
8=8
Step-by-step explanation:
The formula is 4+.5(x)=
So multiply 0.5 by 2 which gives you 1 then add 4 which gives you 5.
To get 6 for 4, you multiply 0.5 by 4 which gives you 2 then add 2+4.
for 6, multiply 0.5 x 6=3 and then 3+4= 7
for 8, multiply 0.5 x 8=4 then add 4+4= 8
Glad to help you! :)
