A: 25h
b:20h+30(h-30)
25h=20h+30(h-30)
5h=30h-30^2
-25h=-30^2
25h=30^2
h=900/25
Answer:
Step-by-step explanation:
115+4n-5=180 degree (being straight line)
110-4n=180
4n=180-110
n=70/4
n=17.5
therefore the value of n is 17.5 degree
substitute the value of n
4n-5
4*17.5-5
70-5
65
The interquartile range (IQR) can be found by finding the difference of the upper and lower quartiles
Answer:
I think 5 and 5 are equal so the angles are equal which are 70,70
Step-by-step explanation:
70+70+x=180
140+x=180
x=40
