Answer:
b=8
Step-by-step explanation:
This is a right triangle, as we can see from the box in the corner.
We can use Pythagorean theorem to find the unknown side
a^2 +b^2 = c^2
where a and b are the legs and c is the hypotenuse
15^2 +b^2 = 17^2
225 + b^2 =289
Subtract 225 from each side
225-225 + b^2 = 289-225
b^2 =64
Take the square root of each side
sqrt(b^2) = sqrt(64)
b = 8
I think it’s 9.5 because it’s a square so all the sides should be equal and you divide 38 by 4 because it has 4 sides

Answer:
R= 20.88 ft
Step-by-step explanation:
See the diagram attached, this satisfies the condition, ΔKLM is enclosed in a circle of radius R.
LN=16 ft (given)
The value of KM is 2R because as the ∠KLM forms an angle of 90°, therefore, the line KM passes through the center.
Area of a triangle =
Now let's find he area of the ΔKLM=
=
Also the area can be found out by =( As KLM is a right angled triangle)
KL= KM cos 25°= 2R cos 25°
LM= KM cos 55°= 2R sin 25°
Area= x 2R cos 25°x 2R sin 25 °
= sin 50°
sin 50°= 16R
R sin 50°=16
R= 20.88 ft
