If the acute angles of a right angled triangle have measures 30ᵒ and 60ᵒ then the length of the side opposite to 60ᵒ angles is √

× hypotenuse

units

Step-by-step explanation:

Considering an equilateral triangle, the measure of the angles are 60ᵒ each and the sides have equal length of 2 units. If the equilateral triangle is divided into two equal right triangles, we have angles 30ᵒ, 60ᵒ and a right angle.

Let the value of the side opposite 60ᵒ angle be represented by x., the side opposite the right angle is 2 units, and that opposite the 30ᵒ is 1 unit.

Applying the Pythagoras theorem to determine the unknown side of the triangle, we have;

= +

= +

4 = + 1

= 4 - 1

   = 3

⇒ x =

The length of the side opposite 60ᵒ angle is units.

it should be a and d. lmk if i'm wrong xd

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.
