Decide if there is a triangle whose angles have these measures in degrees: 60, 60, 60 90, 90, 45 30, 40, 50 90, 45, 45 120, 30, 30 what is the answers?

A

Step-by-step explanation:

Rule: In a triangle, the sum of the three interior angles always is 180° (degrees).

A. 60, 60, 60. If we sum Angle A + Angle B + Angle C= 180 degrees. Thence, this is a triangle with all three internal angles congruent to each other and are each 60°. This triangle is called equilateral.

B. 90, 90 ,45. If we sum Angle A + Angle B + Angle C= 225 degrees. Thence, this is not possible to draw as a triangle.

C. 30, 40, 50. If we sum Angle A + Angle B + Angle C= 120 degrees. Thence, this is not possible to draw as a triangle.

D. 90, 45, 45. If we sum Angle A + Angle B + Angle C= 180 degrees. Thence, this is a triangle with one angle of 90 degrees ir right angle. That is why we call this a rectangular triangle.

E. 120. 30, 30. If we sum Angle A + Angle B + Angle C= 180 degrees. Thence, this is a triangle.

step-by-step explanation:

this woman was an important writer and propagandist during the american revolution. she was a member of the committee of correspondence (in fact the committee was formed in her home) and was an advisor to many of the revolutionary leaders, including george washington and john adams. who was this revolutionary woman?
