In an isosceles triangle the vertex angle is half the base angle

1.	In an isosceles triangle the vertex angle is half the base angle
Answer» Answer: VERTEX angle = 36⁰ BASE angle = 72⁰ Step-by-step explanation: let vertex angle be X let base angle be y we know both base angles are equal since it is an isosceles triangle atq x = 2y --- (1) also, x+ x+ y= 180⁰ 2x + y = 180⁰ 4y + y = 180⁰ --- (from (1)) y = 180⁰/5 y = 36⁰ so vertex angle = 36⁰ x = 2y so base angle = 72⁰ kindly mark as BRAINLIEST

Answer:

VERTEX angle = 36⁰

BASE angle = 72⁰

Step-by-step explanation:

let vertex angle be X

let base angle be y

we know both base angles are equal since it is an isosceles triangle

atq

x = 2y --- (1)

also,

x+ x+ y= 180⁰

2x + y = 180⁰

4y + y = 180⁰ --- (from (1))

y = 180⁰/5

y = 36⁰

so vertex angle = 36⁰

x = 2y

so base angle = 72⁰
