Answer:

Unlike the previous problem, this one requires application of the Law of Cosines.  You want to find angle Q when you know the lengths of all 3 sides of the triangle.

Law of Cosines:  a^2 = b^2 + c^2 - 2bc cos A

Applying that here:

                          40^2 = 32^2 + 64^2 - 2(32)(64)cos Q

Do the math.  Solve for cos Q, and then find Q in degrees and Q in radians.

Answer:

x = 30

Step-by-step explanation:

this is an isosceles triangle, which mean that PRQ and PQR are equal.

all sides of a triangle equal 180.

using this, you can make the following equation:

x + (2x + 15) + (2x + 15) = 180

<em>combine like terms</em>

5x + 30 = 180

<em>subtract 30 from both sides</em>

5x = 150

<em>divide both sides by 5</em>

x = 30

Actually help on this one plz
user100 [1]
Given the fact that AB≈AD, then 35 is also the angle measure of ADB. The sum of the angles of a triangle =180. 35+35=70. 180-70=110

X=110°

Sas<br> Asa<br> These triangles cannot be proven congruent<br> Help please
AlekseyPX
AAS rule can prove these triangles are congruent cuz u see two angles are marked as equal to each other but the side that’s overlapped on each other(the line the triangles are sharing) shows that the side is equal length to each other.
