Answer:

7.75

Step-by-step explanation:

(I'm assuming you need to find the missing side of the triangle)

To find missing values in a right angle. we will use the pythagoras theorem which states that:

h^2 = a^2 + b^2

16^2 = 14^2 + b^2

256 = 196 + b^2

256 - 196 = b^2

60 = b^2 (take sqaure root)

b= 7.75

Answer:

7.75

Step-by-step explanation:

*I’m a big starter to brainly so I’ll appreciate if I can get brainliest please thank you*

Solve the right triangle is a incomplete question. Instead the correct question should’ve been: “Solve for the missing side length”.

Two things we need to understand for this

• Pythagorean theorem
• A, b and c sides
——————————————————————

Pythagorean theorem: a formula used to solve for a missing side length.

Pythagorean theorem = a^2 + b^2 = c^2 where a^2 would be 14 b^2 would be missing side and c^2 would be 16.

Makes sense cause the two sides added (a^2 & b^2) add up to c^2 which is the largest side.

Now we’re going to get right into the steps!

Step 1. Find the missing side length of the right triangle

a^2 + b^2 = c^2

Substitute the side lengths to the formula

14^2 + b^2 = 16^2

Simplify the exponents

196 + b^2 = 256

Solve for b^2

b^2 = 256 - 196

b^2 = 60

Note: that’s not the final answer that is just side b being squared now to undo the square we must square root 60.

Sqrt rt 60 = 7.75

So the missing side length of the triangle would be 7.75

What is the radius of a sphere if its surface area is 2,122.64 square inches? (Use 3.14 for π.) 11 in. 13 in. 121 in. 169 in.

crimeas [40]

To solve this, we are going to use the surface are of a sphere formula: $A=4 \pi r^2$
where
$A$ is the surface area of the sphere
$r$ is the radius of the sphere

We know for our problem that $A=2122.64$ and $\pi =3.14$ , so lets replace those vales in our formula:
$A=4 \pi r^2$
$2122.64=4(3.14)r^2$
$2122.64=12.56r^2$
Now, we just need to solve our equation for $r$ :
$\frac{2122.64}{12.56} =r^2$
$r^2=\frac{2122.64}{12.56}$
$r^2=169$
$r=+or- \sqrt{169}$
$r=13$ or $r=13$
Since the radius of a sphere cannot be a negative number, $r=13$ .

We can conclude that the radius of a sphere with surface area <span>2,122.64 </span> $in^2$ is 13 in.
