Question

8. One of the angles of a triangle measures 80° and the other two angles are equal.
Find the measure of each of the equal angle angles.​

Answer 1

Answer:

its very easy

ans= 50°

Step-by-step explanation:

let the angles be x , y & z

x = 80°

y=z

x+y+z = 180°

80 + y+ y = 180° (y=z)

2y = 180°-80° = 100°

y = 50° = z

Answer 2

$\huge\underline{\underline{\bold{\red{A}\green{n}\orange{s}\pink{w}\blue{e}{r}}}}$

$\sf\large\underline\purple{Given:)}$

• one angle of a triangle =80°

$\sf\large\underline\purple{to}$$\sf\large\underline\purple{find:)}$

• two angles of triangle which is equal

$\sf\large\underline\purple{solution:)}$

we know that sum of all angles of triangle is 180°

let the second angle be x

and third angle be x

then,

80° +x+ y= 180°

(we understand x = y)

so, 2x = 180° - 80°

2x = 100

$x = \frac{100}{2}$

x = 50 °

so, angels are 80° , 50° ,50°

$\sf\large\underline\purple{let's}$$\sf\large\underline\purple{verify}$$\sf\large\underline\purple{it:)}$

we know that sum of all angles of triangle is 180°

so , 80° + 50° + 50° = 180°

yes, In this question we found sum of all angles of triangle is 180° .

so, it is correct.

hence, we do it !
