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
Answer:
im pretty sure 8.2cm
Step-by-step explanation:
<span>We all know that the interior angles of a triangle sums up to 180</span>°. To get the missing angle, we simply subtract the sum of the given angles from 180°
<span>
Similar triangles have the same measure of angles.
Triangle 1: 80°, 62° </span>→ 180 - 80 - 62 = 38°<span>
Triangle 2: 62°, 38° </span>→ 180 - 62 - 38 = 80° SIMILAR TRIANGLES<span>
Triangle 1: 29°, 47° </span>→ 180 - 29 - 47 = 104°<span>
Triangle 2: 91°, 76° </span>→ 180 - 91 - 76 = 13° NOT SIMILAR<span>
Triangle 1: 100°, 45° </span>→ 180 - 100 - 45 = 35°<span>
Triangle 2: 25°, 45° </span>→ 180 - 25 - 45 = 110° NOT SIMILAR
