Question

two angles of a triangle measure 90 degree and 30 degree the measure of third angle is​

Answer 1

Answer:

$\huge\underline{\overline{\mid{\bold{\red{Solution:-}}\mid}}}$

Given:-

• First angle➝90⁰
• Second angle➝30⁰

To find:-

• Measure of third angle

Let the third angle be x

Therefore:

:➝90⁰+30⁰+x=180⁰

:➝x=180⁰-120⁰

:➝x=60⁰

• Hence the third angle is 60⁰

Hope it helps you ✔️✔️

Answer 2

Answer:

Let the angles of the triangles be <A, <B& <C

=> <A + <B +<C = 180°( angle sum property)

=> 90°+30°+<C =180°

=> 120° +<C =180°

=> <C = 180°-120°

=> <C = 60°

So, the third angle is 30°
