Lana71 [14]

Answer:

10a: △ABC is an Equilateral triangle with all acute angles.

10b: △BCD is A scalene triangle with all acute angles.

10c: △BDE is An Isosceles triangle with one obtuse angle.

Step-by-step explanation:

10) Looking at the diagram at the bottom left;

- △ABC has 3 equal internal angles and as such, it means it will have 3 equal angles.

Thus, we can classify it as; Equilateral triangle with all acute angles.

- △BCD has 3 unequal angles. Thus, it's 3 sides are not equal. Also all the angles are less than 90°.

We can classify it as;

A scalene triangle with all acute angles

- △BDE has 2 equal angles and one angle greater than 90°. This means it has 2 equal sides.

Thus, we can classify it as;

- An Isosceles triangle with one obtuse angle.

ahrayia [7]

Answer:

  4 chocolates

Step-by-step explanation:

Before Luke started eating, there were 8. This is 2/3 of what Sara had to start with, so she started with 12. That is 3/4 of what Mike started with, so he started with 16.

Jill left 4/5 of what she started with, so she must have started with 20. Jake ate 1/6 and left 5/6, so 20 is 5 times the number Jake ate.

Jake ate 4 chocolates.

___

Jill ate 4; Mike ate 4; Sara ate 4; and Luke ate 4.

Find the area of a regular hexagon with a said length of 10 centimeters and a apothem of 5 spuare root 3
erma4kov [3.2K]

Answer:

C

Step-by-step explanation:

the area (A) of the hexagon can be calculated as

A = \frac{1}{2} pa ( p is the perimeter and a the apothem )

p = 6 × 10 = 60 and a = 5\sqrt{3} , then

A = \frac{1}{2} × 60 × 5\sqrt{3}

   = 30 × 5\sqrt{3}

   = 150\sqrt{3}

   ≈ 259.8 cm² ( to the nearest tenth )
