In right triangle ΔABC, ∠C is a right angle, AC = 20 and m∠A = 41º. Find AB to the nearest tenth. I NEED HELP ASAP
PLEASE STEP BY STEP

AB = 26.5º

Step-by-step explanation:

cosA = adj/hyp

cosA = AC/AB

cos41 = 20/AB

Multiply both sides by AB

AB * cos41 = 20

Divide both sides by cos41

AB = 20/cos41

AB = 26.5º

Explanation:

ΔABC is right in the angle ∠C

in this case AB is the hypotenuse of the triangle ABC

according to the given data we will use the length of AC which is the adjacent side to the angle ∠A and the Cosine of the angle ∠A in the following formula:

the hypothenuse = adjacent side / cosine of the angle

AB = 20 / cos(41°)

AB = 26.5

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify

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.
