Enter a range of values for x please help me

Mathematics
1 answer:
Brums [2.3K]3 years ago
4 0

Answer:

-5 < x < 9

Step-by-step explanation:

By Hinge theorem,

"If two sides of a triangle are congruent to the two sides of another triangle, and the included angle of one triangle is larger than the included angle of the second, then the 3rd side of triangle one will be larger than the third side of the second"

23 > 21

Therefore, 42° > (3x + 15)°

42° - 15° > 3x

27 > 3x

9 > x

And (3x + 15) > 0

3x > -15

x > -5

Therefore, range for x will be,

-5 < x < 9

Anuta_ua [19.1K]

Answer:

It's 16m

Step-by-step explanation:

Let's say the missing side is C, and since the triangle is right-angle triangle, you can use Pythagoras theorem. Which is

C squared is equal to A squared plus B squared

Like this: c^2 = a^2+b^2

Then

c^2= (10)^2 + (12)^2

c^2= 100 + 144

c^2= 244

c=

\sqrt{244}

c = 15.6

Hope this helps :)

What is an equatiom for the line with slope 2/3 and y-intercept 9​
earnstyle [38]

Answer:

y = (2/3)x + 9

Step-by-step explanation:

Equation of a straight line is y = mx + b. You are trying to finish the equation.

Note that:

m = slope = 2/3

b = y-intercept = 9

Plug in the corresponding numbers to the corresponding variables:

y = mx + b --> y = (2/3)x + 9

y = (2/3)x + 9 is your equation.

Find the diameter of a cone that has a volume of 104.67 cubic inches and a height of 4 inches. Use 3.14 for pi.
Lady bird [3.3K]

Answer:

Step-by-step explanation:

The volume of a cone is

V=\frac{1}{3}\pi r^2h

Filling in what we have:

104.67=\frac{1}{3}(3.14)r^2(4)  and simplifying a bit:

104.67=\frac{1}{3}(12.56)r^2

Multiply both sides by 3 to get:

314.01=12.56r^2

Divide both sides by 12.56 to get:

25.00079618=r^2 and take the square root of both sides to find the radius:

r = 5

If the radius is 5 and the radius by definition is half the diameter, then the diameter is 10 inches.
