Question

if one angle of the triangle is 80 degree and other two angle are in the ratio 1 ratio 3 find the angle
​

Answer 1

Answer:

since sum of all angle of triangle =180degree

let ratio be 1x and 3x respectively

then,1x+3x+80degree =180degree

4x=180-80degree

x=100/4

x=25

therefore,1x=25degree

3x=3×25

=75degree

Answer 2

Answer:

ALL ANGLES ARE 80 , 25 and 75 DEGREES.

Step-by-step explanation:

$let \: the \: other \: two \: angles \: be \: x \: \: \: and \: \: \: 3x. \\ \\ then \: by \: angle \: sum \: property \: of \: a \: triangle \\ \\ 80 + x + 3x = 180 \\ \\ 4x = 100 \\ \\ x = 25 \\ \\ therefore \: the \: two \: angles \: are \: \: 25 \: degrees \: \: and \: \: \: 75 \: \: \: degrees.$
