the third angle. The measure
of third angle is
equal to​

Answer 1

Answer:

the angle is equal to hypotenuse

Answer 2

Answer:

• Third angle = 90°

Step-by-step explanation:

Given:

• Sum of two angles of an triangle is equal to the third angle.

To Find:

• The measure of third angle.

Formula used:

• Angle sum property.

Let two angles of triangle be a and b.

∴ Third angle = a + b

Now, by angle sum property.

⇒ 1st angle + 2nd angle + 3rd angle = 180°

⇒ a + b + a + b = 180°

⇒ 2a + 2b = 180°

⇒ 2(a + b) = 180°

⇒ a + b = 180/2

⇒ a + b = 90°

Hence, third angle = 90°
