"<span>z˄2 − 3" because x squared is z^2, and 3 less of it would mean to subtract it from 3</span>
This is a quadratic so if you want to find the solutions, use the quadratic formula. Google quadratic formula and videos on it and how to use it will pop up.
The correct answer is 42.
5 • 8 = 40
40 + 2 = 42
7712 divided by 32
= 7712/32= 241
First divide by 2 to give
3856/16
Divide again by 2 =
1928/8 and again by 2
964/4 and again by 2 to give
482/2 and divide by 2 again to give 241
Answer: Angle K measures 34° (approximately)
Step-by-step explanation: (Please refer to the picture attached).
The triangle has been described as having sides JKL and one of the angles identified as angle JLK measures 105 degrees. Also one of the sides labelled JK measures 4.7 while another side JL measures 2.7.
The law of sine (or sine rule) shall be applied as stipulated in the question and this is most appropriate because this rule in mathematics applies when you have a triangle with two sides and one of the angles (facing one of the two sides) given, or when you have two angles and one side facing one of the angles given.
In this question, you have been given two sides, JK and JL and you also have angle K (facing side JL) given. The Sine Rule is stated as follows
SinA/a = SinB/b = SinC/c
(Note that a/SinA = b/SinB = c/SinC is also very correct)
Substituting for the known values, our sine rule can now be re-written as
SinL/4.7 = SinK/2.7
Sin 105/4.7 = SinK/2.7
(Sin 105 * 2.7)/4.7 = SinK
(0.9659 * 2.7)/4.7 = Sin K
2.60793/4.7 = Sin K
0.5549 = Sin K
Checking the values with a calculator gives you
K = 33.70
K ≈ 34°
Therefore angle K = 34°
