Round to the nearest tenth.
laila [671]

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

<u />

<u>Recall the Law of Cosines</u>

<u />a^2=b^2+c^2-2bc\cdot cos(A)

<u>Identify angles and sides</u>

<u />m\angle A=23^\circ\\a=BC=?\\b=AC=14\\c=AB=6

<u>Solve for side "a"</u>

<u />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

-4(5k-7) +2k= -2(9k+5)
Blababa [14]

Answer:

no solutions

Step-by-step explanation:

-4(5k-7) +2k= -2(9k+5)

Distribute

-20k +28 +2k = -18k -10

Combine like terms

-18k +28 = -18k -10

Add 18k to each side

-18k+18k +28 = -18k+18k  -10

28 = -10

This is never true so there are no solutions
