Answer:

Step-by-step explanation:

KL = 12 because the triangle is isosceles ( base angles are congruent)

KJ = JM = 12 because the triangle is equilateral ( all angles are equal 60°)

the perimeter is

P = 9 + 12 + 12 +12 = 9 +36 = 45

Answer:

D: 768

Step-by-step explanation:

First, he divides a piece of paper in half.

$1 \div \frac{1}{2} = 2$

He gets two pieces.

Next, he cuts each of the pieces into three parts.

$2 \div \frac{1}{3} = 6$

Thirdly, he cuts each of the 6 pieces into 8 pieces.

$6 \div \frac{1}{8} = 48$

Lastly, he divides each piece into 16 parts.

$48 \div \frac{1}{16} = 768$

He has 768 pieces in the end. (D)

Round to the nearest tenth.

Answer:

8.2 units

Step-by-step explanation:

Given that the only information for our triangle are 2 sides and 1 angle, we must use the Law of Cosines to find side BC

Recall the Law of Cosines

$a^2=b^2+c^2-2bc\cdot cos(A)$

Identify angles and sides

$m\angle A=23^\circ\\a=BC=?\\b=AC=14\\c=AB=6$

Solve for side "a"

$a^2=b^2+c^2-2bc\cdot cos(A)\\\\a^2=14^2+6^2-2(14)(6)\cdot cos(23^\circ)\\\\a^2=196+36-168cos(23^\circ)\\\\a^2=222-168cos(23^\circ)\\\\a=\sqrt{222-168cos(23^\circ)}\\ \\a\approx8.2$

Therefore, the length of line segment BC is about 8.2 units
