It's a right triangle. Use the pythagorean theorem. 36^2+r^2=(r+12)^2. r=48.
Answer:
C. 647 square units
Step-by-step explanation:
To find the shaded area, subtract the area of the unshaded square from the area of the octagon.
<u>Area of the octagon</u>

where:
- n = number of sides
- l = length of one side
- a = apothem
Given:
Substitute the given values into the formula and solve for A:



<u>Area of the square</u>

<u>Area of the shaded region</u>
= area of the octagon - area of the square
= 815.88 - 169
= 646.88
= 647 square units (nearest square unit)
Answer: 20.57142857
Step-by-step explanation:
148 = 3x + 3 + 4x + 1
Step one: combine like terms
148 = 7x + 4
Step 2: Subtract the 4 over to 148
144 = 7x
Step 3: Divide 7 on both sides
20.57142857 = x
Answer:
g(x) = -|x| + 1
Step-by-step explanation:
Let g(x) be the transformation function
-|x| reflects f(x) across the x-axis. Add 1 to move the result up one unit
So, g(x) = -|x| + 1
Answer:
x=111
Step-by-step explanation:
the sum of angles of triangle is 180
find te missing angle in the triangle first :
180-29-82=69
find x now: the measure of straight angle is 180:
x+69=180
x=180-69=111
this one way to find x
another way is that x=82+29=111
