Triangle J K L is shown. Angle J L K is 105 degrees. The length of J K is 4.7 and the length of J L is 2.7.
cluponka [151]

Answer:

The approximate measure of angle K is 34°

Step-by-step explanation:

In ΔJKL

∠L = 105°

JK = 4.7

JL = 2.7

Sine Rule:

\frac{SinA}{a} = \frac{SinB}{b}= \frac{SinC}{c}

So,\frac{SinL}{JK} = \frac{SinK}{JL}\\\frac{SinL}{4.7} = \frac{SinK}{2.7}\\\frac{Sin 105}{4.7} = \frac{SinK}{2.7}\\\frac{Sin 105 \times 2.7}{4.7} = SinK\\\frac{(0.9659 \times 2.7)}{4.7} = Sin K\\\frac{2.60793}{4.7} = Sin K\\0.5549 = Sin K\\Sin^{-1}(0.5549)= K\\K = 33.70

K ≈ 34°

So, Option B is true

Hence The approximate measure of angle K is 34°

Given -2x-8>-12 determine the largest integer that satisfies the inequality
Ann [662]

-2x - 8 > -12

-2x - 8 + 2x > -12 + 2x ...... add 2x to both sides

-8 > -12 + 2x

-8+12 > -12+2x+12 .... add 12 to both sides

4 > 2x

2x < 4 ..... flip both sides so that the x term is on the left side

2x/2 < 4/2 .... divide both sides by 2

x < 2

This describes the set of x values such that x is less than 2.

The largest integer that x can be is x = 1. The value of x cannot be 2 because we don't have an "or equal to" as part of the inequality sign.

Final Answer: 1
