Answer:
r = 30°
Step-by-step explanation:
According to the Exterior Angle Sum Theorem, the exterior angle, which is 90°, is equal to the 2 interior angles, which are 60° and <em>r°</em>. We know that the angle next to the exterior angle is 90°, and since all angle sums add up to 180°, <em>r</em> = 30°.
Answer: the answer is option B. or h(x) = 9x - 18
Step-by-step explanation:
Answer:
Area = 166cm² (Approximately)
Step-by-step explanation:
To solve this, let's recall the formula for the area of a REGULAR Hexagon.
The area of a REGULAR Hexagon is expressed as:
A = (3√3 * a²) / 2
Where a is the length of one side of the Hexagon.
a= 8cm.
Area = (3√3 * 8²) / 2
Area = (3√3 * 64) / 2
Area = (192√3) / 2
Area = 332.55 / 2
Area = 166.28cm²
Area = 166cm² (Approximately)
First and third options are correct
7/8 x = 21
7x = 21×8
7x = 168
x = 24
