We know:
a, b, c - the lenght of sides of a triangle
a + b > c; a + c > b; b + c > a
We have:
a = 14 in; b = 4 in
check b + c > a:
c = 10in → 4 + 10 = 14 NOT
c = 11 in → 4 + 11 = 15 > 14
Answer: 11 in
Answer:
Are there any other steps?
Step-by-step explanation:
That seems like not enough info
49 and 63 can both be divided by 7
49/7=7
63/7= 9
7/9
Answer:
Area of octagon = 100 - 2 = 98 cm²
Step-by-step explanation:
Area of octagon = area of square - area of 4 triangles that are formed in four corners
Area of square:
Side = Width of the octagon = 10 cm
Area = side * side
= 10 * 10
= 100 cm²
Area of triangle:
Base = 2cm
height = 2 cm
Area =
=
= 2 cm²
Area of octagon = 100 - 2 = 98 cm²
