Answer:
11.5
Step-by-step explanation:
midrange formula= (high + low)/2
(18 + 5)/2
=23/2
=11.5
5.50, I think I’m right I just added 30 percent of 4.25 to 4.25
The angles are 27°, 27° and 126°
let the 2 equal angles be x then the third angle = 3x + 45
sum of 3 angles = x + x + 3x + 45 = 5x + 45 = 180
hence 5x = 180 - 45 = 135⇒ x= 135/5 = 27
the angles are 27°, 27° and 3x + 45 =81 + 45 = 126°
