Determine whether each triangle should be solved by beginning with the law of sines or the law of cosines. then solve each triangle. round measures of sides and angles to the nearest tenth after calculating. a = 8, b = 7, c = 4 question 3 options: law of cosines; a ≈ 89°, b ≈ 61°, c ≈ 30° law of sines; a ≈ 89°, b ≈ 61°, c ≈ 30° law of sines; a ≈ 30°, b ≈ 61°, c ≈ 89° law of cosines; a ≈ 61°, b ≈ 89°, c ≈ 30°

Law of Cosines; A ≈ 61°, B ≈ 89°, C ≈ 30°

Step-by-step explanation:

In this problem the given values are the length sides of the triangle, therefore, the triangle should be solved by beginning with the Law of Cosines

step 1

Applying the law of cosines find the value of angle C

we know that

we have

substitute the values and solve for cos(C)

step 2

Applying the law of cosines find the value of angle B

we know that

we have

substitute the values and solve for cos(B)

step 3

Find the measure of angle A

we know that

The sum of the interior angles of a triangle must be equal to 180 degrees

so

we have

substitute and solve for A

you already gave the answer

step-by-step explanation:

the correct answer is a) they believe they have a "just cause."

islamic terrorists justify their violent actions because they believe they have a "just cause."

every act of terrorism of islamic sects is done “in the name of allah”. that justifies their actions. islam people who commit those terrorist attacks are not afraid to die. that is why the attacks have horrible consequences. they know they are going to die and they are proud to do it because it is in the name of allah, so it is justified and is for a “good cause.”

since the very beginning of the conflict with israel, islam is fighting a “sacred war”, respecting the words stated in the qur’an. they fight against the domination of the western countries and to defend their occupied territories.
