Answer:
A
Step-by-step explanation:
Answer:
4588 [in²].
Step-by-step explanation:
1) the given octagon can be imagined as 8 triangles (see the attachment). In order to calculate the required area of the octagon, it is enough to calculate the area of one triangle then increase it 8 times:
2) area of one triangle is:
37*31/2 [in²].
3) the required area of the octagon is:
31*37*8/2=31*37*4=4588 [in²].
Answer:
17.40 seconds
Step-by-step explanation:
You would you the quadratic formula to get 17.40 seconds
The measure of the three missing angles in the given rhombus are:
x = 122°
z = 58°
y = 122°
<h3>What is a Rhombus?</h3>
A rhombus is a quadrilateral with four interior angles. In a rhombus, the opposite angles are congruent while the adjacent angles are supplementary to each other.
x and 58° are adjacent angles and are therefore supplementary.
x = 180 - 58 = 122°
z = 58° (opposite angles)
y = x = 122° (opposite angles)
