Answer:
Sqrt 245
Step-by-step explanation:
That's the answer
According to Pythagoras' Theorem
[tex]h^{2} = a^2 + b^2[/tex]
[tex]h^{2}[/tex] [tex]= 7^{2} + 14^2[/tex]
[tex]h^{2}[/tex] = 49 + 196

According to diagram x = sqrt 245
What is Pythagoras' hypothesis?
Pythagorean hypothesis, the notable mathematical hypothesis that the amount of the squares on the legs of a right triangle is equivalent to the square on the hypotenuse (the side inverse the right point) — or, in recognizable logarithmic documentation, a2 + b2 = c2.

A skateboard ramp has a slope of 4/9. What is the measure of the angle the ramp forms with the ground
Answer:
Step-by-step explanation:
tanθ = 4/9
θ = arctan(4/9) ≈ 23.96°
The measure of the angle the ramp forms with the ground is :
-Angle is 23.96 degrees.
"Measure of the angle"Let the angle is = x
We know that tan(x) is the slope.
tan(x)=\frac{4}{9}
tanθ = 4/9θ
tanθ = arctan(4/9)
tanθ≈ 23.96°

x = [?]
Enter
Answer:
x = 6
Step-by-step explanation:
sin 30° = 3/x
0.5 = 3/x
.5x = 3
x = 3/.5
x = 6
The indicated side of the right-angled triangle is 6.
What is a right-angled triangle?A triangle is said to be right-angled if one of its inner angles is 90 degrees, or if any one of its angles is a right angle.
Given:
The triangle is a right-angled triangle.
So, we know,
SinФ = perpendicular / hypotenuse.
And here, perpendicular = 3 unit
And hypotenuse = x unit
Substituting the values,
Sin30° = 3/x
1/2 = 3/x
x = 6
Therefore, the value of x is 6.

a^2+b^2=c^2
height of a cone is 30cm, its slant height is 32 cm, then the radius is- ?
Given:
Height of a cone is 30cm, its slant height is 34 cm.
To find:
The radius of the cone.
Solution:
Using the Pythagoras theorem, the relation between Height, radius and slant height is
[tex]r^2+h^2=l^2[/tex]
[tex]r^2=l^2-h^2[/tex]
Where, r is radius, h is height and l is the slant height.
Putting the given values, we get
[tex]r^2=(34)^2-(30)^2[/tex]
[tex]r^2=1156-900[/tex]
[tex]r^2=256[/tex]
Taking square root on both sides.
[tex]r=\pm\sqrt{256}[/tex]
[tex]r=\pm 16[/tex]
Radius cannot be negative. So, r=16 cm.
Therefore, the correct option is b.
