FIND THE TWO X
Answers
Step-by-step explanation:
It has given that, sides of a right angled triangle are ; 6 cm, 8cm and 10 cm.
we have to find the length of perpendicular drawn to the hypotenuse from the opposite vertex.
solution : let length of perpendicular drawn to the hypotenuse is x cm.
let right angled triangle is ∆ABC where B is right angle. and we draw a perpendicular B to AC which touches AC at T.
here, ∠BAT = ∠BAC
and ∠BTA = ∠ABC
so, ∆ATB ~ ∆ABC
then, AB/AC = BT/BC
⇒6cm/10cm = BT/8 cm
⇒BT = 48/10 = 4.8 cm
Therefore the length of perpendicular drawn to hypotenuse is 4.8 cm
Answer:
1st x =400
2nd x=300
Step-by-step explanation:
−176+422+76+−22=−100+a=b
Consider the first equation. Add −176 and 422 to get 246.
246+76−22=−100+x
Add 246 and 76 to get 322.
322−22=−100+x
Subtract 22 from 322 to get 300.
300=−100+x
Swap sides so that all variable terms are on the left hand side.
−100+x=300
Add 100 to both sides.
x=300+100
Add 300 and 100 to get 400.
x=400
Consider the second equation. Insert the known values of variables into the equation.
−100+400=x
Add −100 and 400 to get 300.
300=x
Swap sides so that all variable terms are on the left hand side.
x=300
The system is now solved.
1st x =400
2nd x=300
