Answer:
x = 3
Step-by-step explanation:
To find the x-coordinate, substitute y = 8 into the equation abd solve for x
5x - 7 = 8 ( add 7 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3
Thus (3, 7) is a solution to the equation
Answer:
The length of KH is 6 units and OH is 6.3 units.
Step-by-step explanation:
Given the figure with lengths LO=5 and OK=4. we have to find the length of OH and KH.
In ΔLOH
By Pythagoras theorem
→ (1)
In ΔKOH,
→ (2)
In ΔKHL,

Using eq (1) and (2), we get


⇒ 
⇒ 
Put the above value in eq 2, we get
⇒ KH=6 units.
A=1/2 B×h
285=1/2×B×15
B=38 feet, so the base of the triangle is 38 feet. Hope it help!
