Answer:
option d is the correct answer
Step-by-step explanation:
use formula for finding sum of all interior angles of regular polygon i.e. (n-2)×180 where n is no of sides of regular polygon then divide it by no. of sides of regular polygon to find measure of one angle of regular polygon and then subtract it from 180° to find the answer

Answer:
2)105°
Step-by-step explanation:
In this parallelogram, J should be congruent to L (J=L). We can solve this problem if we find out the value of L.
The sum of the adjacent angle of the parallelogram will be equal to 180 degrees, so the equation is
L + M = 180
M=180- L
If L exceeds M by 30 degrees then the equation will be
L=M +30
If you combine both equations, it will be
L+30 = M +30
L+30 = (180- L) +30
L + L= 180 + 30
2L= 210
L=105
Answer:
400 %
Step-by-step explanation:
X²+15x+36<0
at first solve quadratic equation
D=b²-4ac= 225-4*1*36= 81
x=(-b+/-√D)/2a
x=(-15+/-√81)/2= (-15+/-9)/2
x1=(-15-9)/2=-12
x2=(-15+9)/2=-3
we can write x²+15x+36<0 as (x+12)(x+3)<0
(x+12)(x+3)<0 can be 2 cases, because for product to be negative one factor should be negative , and second factor should be positive
1 case) x+12<0, and x+3>0,
x<-12, and x>-3
(-∞, -12) and(-3,∞) gives empty set
or second case) x+12>0 and x+3<0
x>-12 and x<-3
(-12,∞) and (-∞,-3) they are crossing , so (-12, -3) is a solution of this inequality
