Question

the vertical angle of an isosceles triangle is 110 . find the measurement of its base angles​

Answer 1

Answer:

$so \: the \: three \: angles \: will \: be \: \\ 110 \: x \: and \: x$

$because \: angles \: opposite \: \\ equal \: sides \: are \: equal$

$110 + x + x = 180 \\ (angle \: sum \: property)$

$2x + 110 = 180$

$2x = 180 - 110 = 70$

$x = 35$

Answer 2

Answer:

35

Step-by-step explanation:

Let the two base angles be x

By angle sum prop. of triangle,

x+x+110=180

2x+110=180

2x=180-110

2x=70

x=70/2

x=35

Thus ,the base angles are 35.
