In order to find the area of a triangle you have to multiply the base with the height then divide by 2.
hope this helps
The supplementary angle to 69 degrees would be 111 DEGREES.
because it has to add up to 180 (69 + 111 = 180)
You were right already it’s A
"interverted" or "inverted?"
The vertical height of an inverted cone with base diameter 6 cm and slant height of 6 cm can be found using the Pyth. Thm. Draw or imagine a triangle whose height is h and whose base is 3 cm (not 6) and whose hypotenuse is 6 cm.
Then h^2 + (3 cm)^2 = (6 cm)^2, or h^2 + 9 cm^2 = 36 cm^2, or h^2 = 27 cm^2.
Then the height of the triangle, as well as of the cone, is h = +√27, or
h = +3√3.
