Answer:
Sum of all angles is 720°
x=105
∠H=110°
∠I=100°
∠K=135°
Step-by-step explanation:
The sum of all inetrior angles is 720°
So,
140+105+130+(x+5)+(x-5)+(x+30)=720
375+3x+30=720
405+3x=720
3x=720-405
3x=315
∴x=105
∠H=x+5
∠H=105+5
∴∠H=110°
∠I=x-5
∠I=105-5
∴∠I=100°
∠K=x+30
∠K=105+30
∴∠K=135°

Answer:If my calculations are correct and my rounding I would show you my work but I cant upload the picture but I think about
38
Step-by-step explanation:
I=Hope I helped if so can I please have brainliest :)
To calculate for the standard deviation given the
probability, we use the formula:
s = sqrt (n p q)
where s is standard deviation, n is number of samples = 11,
p is probability of success = 0.7, q = 1 – p = 0.30
s = sqrt (11 * 0.7 * 0.3)

Answer:
38 cm
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of all its sides.
We have two unknown length, so let's find their lengths first.
x= 10 -6= 4 cm
y= 9 -2= 7cm
Let's add all the lengths together to find the perimeter:
Perimeter
= 9 +10 +2 +6 +7 +4
= 38 cm
