Atriangle is such that the largest angle is 3 times the smallest angle. the third angle is 23 less than the largest angle. find the measure of each angle.

largest angle:  3x

smallest angle:  x

third angle:  3x - 23

The sum of the angles of a triangle equals 180°

(3x) + (x) + (3x -23) = 180

7x - 23 = 180

7x = 203

x = 29

largest angle:  3x  = 3(29)  = 87

third angle:  3x - 23   = 3(29) - 23   = 87 - 23   = 64

29°, 64°, 87°

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)

just pick what you think i need more time let me know if this
