Question

the measures of two angles of a triangle are 72° and 58. find the measure of the third angle​

Answer 1

Answer:

Step-by-step explanation:sum pf angles in a triangle=180*

angle A +angle B+angle C=180*

72+58+angle C=180*

130+angle C=180*

angle C =180-130

angle C=50*

Therefore angle C is required angle=50*

Answer 2

$\textbf{\underline{Answer :-}}$

The third angle of the triangle measures 50°

$\textbf{\underline{Explanation :-}}$

$\textsf{\underline{Given :-}}$

One angle = 72°

Second angle = 58°

$\textsf{\underline{To find :}}$

The measure of the third Angle of the Triangle

$\textsf{\underline{Solution :-}}$

A triangle is a three sides closed 2D figure.

Solution according to the property of the triangle : Angle sum property

Angle sum property states that :

All angles of a triangle sum up and make 180°

Consider the missing angle as x

$\tt{\Rightarrow72\degree + 58\degree + x\degree = 180\degree}$

$\tt{\Rightarrow130 + x = 180}$

$\tt{\Rightarrow \: x =180 - 130}$

$\tt{\Rightarrow \: x = 50\degree}$

Therefore the third angle of the triangle measures 50°
