Firstly we need to find m<DNY
m<DNY=(60+90)÷2=75
N9w we can find m<KNY
m<KNY+m<DNY=180°(Because these are adjacent corners)
m<KNY+75°=180°
m<KNY=180°-75°
m<KNY=105°
In this exercise we have assumption:
x-4>0
x>4
from this we know domain : x∈(4,+infinity)
range y∈R
When dividing a decimal by a decimal, you have to move the decimal before you divide but when you divide with whole numbers, you just divide.
Answer:
20
Step-by-step explanation:
3x + x + 100 = 180 (sum of angles on a straight line)
4x = 180-100
4x=80
divide both sides by 4
x=20
