In a triangle all the angles add up to 180 degrees.So we know that
(6x-1)+20+(x+14)= 180
6x+x+14-1+20=180
v v
7x + 13 + 20= 180
v
7x + 33=180
-33 -33
0 147
7x/7 = 147/7
x = 21
x=21
Then you substitute:
(6x-1) (x+14)
(6×21-1) (21+14)
v v
126-1 35
125 degrees / 35 degrees
125+35+20=180

hope it helps...
Step-by-step explanation:
The ratio of a number x and four added to two:
= 4x + 2 = 0
= 4x = -2
= 4x/4 = -2/4
= x = -2/4
= x = -1/2
The probability of guessing 4 right is
.. (5C4)*(1/2)^5 = 5/32
The probability of guessing 5 right is
.. (5C5)*(1/2)^5 = 1/32
So, the probability of guessing 4 or 5 right is
.. (5+1)/32 = 6/32 = 0.1875
it is D: 93/100 i hope this helpss!!!
Perimeter of rectangle = 2(l+w)
let. width = x, length = x+12
So, 100 = 2(x+x+12)
100=2(2x+12)
100=4x+24
4x=76
x=19, y=19+12 = 31
So, Length = 31 m & Width = 19 m
