I need to solve for x btw this box means 90 degrees ​

x = 61°

Step-by-step explanation:

x+29+90 = 180 [This is because all angles in a triangle add up to 180°]

x = 180-29-90

x = 180-119

x = 61°

the answer is 15% decrease

1)is not similar since corresponding sides are not in the same ratio

2)are similar since corresponding sides are in the same ratio and corresponding angles are equal

hope it will
