Question

If the sum of two angles of a triangle is equal to its third angle , determine the measurement of the third angle​

Answer 1

Answer:

sum of two angles of a triangle means

Step-by-step explanation:

x+x=2x

let the third angle be x

sum of measure of all angles if a triangle is 180 degrees

so

x+x+2x=180deg

4x=180 deg

so

180÷4=45 deg

Answer 2

Answer:

90 degree

Step-by-step explanation:

the measurements of three angle of triangle is 180

a+b+c=180

a+b=c=180÷2=90

a+b=c=90
