Area of triangle = 1/2 ABsinC

Since all sides are equal, it means it is an equilateral triangle
⇒All angles are 60°

Area of triangle = 1/2 ABsinC
Area of triangle = 1/2 (3.5)(3.5)sin(60°)
Area of triangle = 5.3 in²

Two angle of a tranigle measure 55 and 20 what is the measure of the third angle

wariber [46]

Answer:

105 degrees

Step-by-step explanation:

Recall that the sum of angles in a triangle is 180 degrees. As such, where a, b and c are the angles of a triangle then

a + b + c = 180 ( all in degrees)

Given that two angles of a triangle measure 55 and 20, let the size of gthe 3rd be T then

55 + 20 + T = 180

simplify

75 + T = 180

Subtract 75 from both sides

T = 180 - 75

T = 105
