Question

25. Two angles of triangle are equal and the third angle is greater than each of these angles by 30°
Find all the angles of the triangle.
​

Answer 1

I think 75°

Step-by-step explanation:

because, if one angle is equal to 30° and the 2 angles equal then, a triangle is 180° then 30°-180° is equal to 75°

Answer 2

Given:

• Two angles of triangle are equal
• The third angle is greater than each of these angles by 30°.

To Find:

• Measure of all the angles of the triangle.

Solution:

Let,

The Two Angles be x°,x°.

Then, The Third Angle is (x+30°)

According To Sum

$→\;{\bf{x+x+(x+30°) = 180°}}$

❂ Sum Of All The Angles Of A Triangle Are 180°.

$→\;{\bf{3x = 180°-30°}}$

$→\;{\bf{x = \cancel{\frac{150°}{3}}}}$

$→\;{\bf{x = 50°}}$

Third Angle ☞ x+30° = 50°+30° → 80°

AnSweR:

Measure of Two Equal Angles ◕➜ $\Large{\red{\mathfrak{50°}}}$

Measure of The Third Angle ◕➜ $\Large{\green{\mathfrak{80°}}}$
