Answer:
x= 6/7z
Step-by-step explanation:
5x + 4z = 10z - 2x
5x + 2x = 10z - 4z
7x = 6z
x = 6/7z
We will determine the length of the segment DF as follows:
*We have that the triangles are similar, and therefore the following is true:
Now, we solve for DF:
From this, we have that the length of the segment DF equals 2.68 units.
Answer:
Linear
Step-by-step explanation:
It is linear as it has degree 1.
1)
x+10<-7
bring 10 to the other side
x<-10-7
x<-17
2)
-3x-4>5
bring -4 to the other side
-3x>9
divide -3 at the other side, since it is negative it changes to less than
x<-3
Answer
Exterior,18°
Interior,162°
Step-by-step explanation:
To calculate exterior,360°÷no of sides, i.e
360°÷20=18°
Interior is gotten by 180°-exterior angle
180°-18°=162°
