Answer:
x=.3
Step-by-step explanation:
3(x-2)=3x -2
(1x-2)=3(-1x)=3x -2
3(-1x)=3x -2
+3x +3x
3*2x=2
6x=2
6x/6=2/6
x=.3
Consider the right triangle in the attached diagram. Using the Pythagorean theorem, you can find the distance marked "a" by
r² = a² + o²
a = √(r² - o²) = √(20² -16²)
a = √(400 - 256) = √144 = 12
The
maximum depth is the difference between r and a, so is (20-12) cm =
8 cm.

Answer:
Step-by-step explanation:
A triangular pyramid has a base with an area of 21.8 square meters, and lateral faces with bases of 7.1 meters and heights of 9 meters. Enter an expression that can be used to find the surface area of the triangular pyramid.
The expression is written as:
Surface Area = Area of the base + 1/2( Perimeter × Slant height)
