Question

two angles of a triangle are equal and its third angle is double of the equal angles find the measures of the three angles of the triangle​

Answer 1

Answer: 45 45 and 90

Step-by-step explanation:

LET equal angles be x and x. The third angle will be 2x.

Hence in the triangle the angles will be x,x and 2x.

Sum of angles in triangle is x+x+2x=180

4x=180

x=45

Therefore angles are 45,45 and 90(2*x=2*45=90)

Answer 2

Answer:

Step-by-step explanation:

the the two equal angles are assumed to be x and the third angle is assumed to be 2x then

solution;

x+x+2x=180 since the total interior angles of the triangle is equal to 180

therefore 2x+2x=180, 4x=180

hence x=45,

the first two equal angles equal to 45 degrees the third which is 2x... 2(45)= 90 degrees
