Answer:
ACB=44°
DCE=35°
BCD=101°
Step-by-step explanation:
ACB is a triangle and all triangles are 180 degrees
78+58=136
180-136=44
DCE is also a triangle
85+60=145
180-145=35
a straight line is 180 degrees, we already know what the other two is.
35+44=79
180-79=101

Answer:
30
%
Step-by-step explanation:
Assumption: the increase is to be expressed as a percentage of 10.
We change from 10 to 13 so the increase is 3 We now need to change this into a percentage.
In fraction form we have increase Original value → 3 10 But we need to change this into the form some number 100 Let the unknown value be x giving: 3 10 ≡ some number 100 = x 100 To change the 10 from 3 10 into 100 we multiply by 10 Multiply by 1 and you do not change the value.
However, 1 comes in many forms.
3 10 × 1 = 3 10 × 10 10 = 30 100 This is the same as 30 × 1 100 but 1 100 is the same as %.
So 30 100 → 30 %
