Help me this is a test help

Always remember that the sum of three angles belongs to triangle equal to 180 degrees,

x+59+84+X+51=180

2x+194=180

2x=180-194

2x=-14

x=-7

measure of angle A=-7+51

=44

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
