Answer:
the answer is 55 degrees
Step-by-step explanation:
1/3+1/2=5/6
and 1/4+1/3=7/12
Answer:
<AED = 60
Step-by-step explanation:
Since triangle ADE is similar to triangle ABC
Angle ADE equals angle ADC
The angles of a triangle add to 180 degrees
<A + <ADE + <AED = 180
36 + 84+ <AED = 180
Combine like terms
120 + <AED = 180
Subtract 120 from each side
120-120 +<AED = 180-120
<AED = 60
The answerer is combining terms in x with constants
that is, 13x + 5 ≠ 18x
13x + 5 + 17x - 4.5 + x
= (13x + 17x + x ) + 5 - 4.5 ← collecting like terms
= 31x + 0.5 ← correct simplification
