We know that,
In a right-angled triangle,
Hypotenuse ² = Base ² + Height ²
1 – 10 ² = 6 ² + X ²
Or, X ² = 10 ² – 6 ²
Or, X ² = 100 – 36
Or, X ² = 64
Or, X = √ 64
Or, X = 8 Units
2– X² = 7² + 3²
Or, X² = 49 + 9
Or, X² = 58
Or, X = √58
Or, X = 7.61 Units ( Approx )
3 – 15 ² = EF ² + 9
Or, EF² = 15 ² – 9 ²
Or, EF ² = 225 – 91
Or, EF ² = 134
Or, EF = √ 134
Or, EF = 11.6 Inches ( Approx)
.II} 1 – Here the length of the ladder will be the hypotenuse.
Hence, Hypotenuse = 13 Metre
.Now, The vertical wall will be the height.
Hence, Height = 12 Metre
Distance of the foot of the ladder to the wall will be the base.
Let base be B.
Now, Hypotenuse ² = Base ² + Height ²
Or, 13² = B² + 12²
Or, B² = 13² – 12²
Or, B² = 169 – 144
Or, B² = 25
Or, B = √25
Or, B = 5 Metre
Hence, the distance of the foot of the ladder from the wall is 5 metre apart.
HEY THERE!!
CORRECT EQUATION:- 3x +1 = y
EXPLANATION :-
1. x = -2
now put this value in the equation 3x+1=y
3× - 2 +1 = y
-5 = y
which is correct so the equation is

Hope it helps you.

22.4 cm
Step-by-step explanation:
2.8 cm x 8 sides = 22.4 cm
Answer:
The volume of tank to the nearest cube is 503 ft³
Step-by-step explanation:
Given that,
Diameter of tank = 8 ft
radius = 4 ft
Height = 10 ft
We need to calculate the volume of tank
Using formula of volume

Where, r = radius
h = height
Put the value into the formula



Hence, The volume of tank to the nearest cube is 503 ft³
