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

h = [tex]\sqrt{245}[/tex]

According to diagram x = sqrt 245

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.

Answer:

x = 140

x = 140

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.

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.

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.

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)

Step-by-step explanation:

(a)

When t = 0 then

f(0) = 31 + [tex]\frac{0}{100}[/tex] = 31 + 0 = 31° F

(b)

When t = 10 , then

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.
