How do you describe the angles in each figure90°straight2.180°acute3.38°ri ght4.125°obtuse some one me

90 is a right angle and is the angle of a corner of a square.

180 is a straight line because i is double a right angle.

38 is an acute angle because it is smaller than 90.

125 is obtuse because it is bigger than 90.

step-by-step explanation:

1) the property is   ixi = a ⇔x = a   o x = -a

4(x-5)+3= 15⇒4x-20+3 = 15⇒4x-17= 15⇒4x = 15+17⇒4x = 32⇒x =32/4= 8

4(x-5) +3= -15⇒4x-20 +3 = -15⇒4x-17= -15⇒4x =-15+17⇒4x = 2⇒x =2/4= 1/2

the values are x =8 and x = 0,5
