Question

find the value of X and y from the given figure.​

Answer 1

Answer:

y = 50

x = 80

Step-by-step explanation:

An isosceles triangle therefore has both two equal sides and two equal angles.

the 2 equal angles are y and and the one next to the 130 degree

so 180- 130 = 50

y = 50

x = 180 - 50 -50 = 80 degree

Answer 2

Step-by-step explanation:

let, the reaming angle be z

• z+130°=180°{being straight angle}
• z=180-130
• z=50°

again,

• z=y { base angle of isosceles triangle are equal}

also,

• x+y+z=180°{ sum of angles of triangle}
• x+50°+50°=180°
• x=180-100
• x=80°

hope it helps.

stay safe healthy and happy.
