Answer:
2.85 in²
Step-by-step explanation:
Area of triangle = 1/2 x base x height
1/2 x 1.9 x 3 = 2.85 in²
Answer:
x = 2
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
Sum the 3 angles and equate to 180
6x + 15 + 90 + 63 = 180
6x + 168 = 180 ( subtract 168 from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
Answer:
Step-by-step explanation:
For all shapes, the surface area will go up by a factor of 9 (3^2). This is true of spheres, cones, cubes, pyramids, torusses, everything.
The surface area of any body is proportional to the square of any linear dimension. Triple a linear dimension and you get a 9 fold increase in surface area. This is as true for pretzels as it is for spheres and cubes.
