You idiot you answered your own question!
Answer:
148⁰
Step-by-step explanation:
M< EDF = M< DFE (because the two angles are equal because the triangle has two equal sides)
2x + 8 = 3x + 4
8 – 4 = 3x - 2x
4=x or x=4
So M< EDF= 2x4+8 = 16⁰
So M< EDF + M< DFE= 32⁰
180⁰- 32⁰ = 148⁰
First you need to get 3% of 7 so
7x0.03= 0.21
then you need to add that 3% onto 7
7+0.21=7.21
therefore the door frame is now 7.21 feet high
Perimeter = Length + Length + Width + Width
Area = Length x Width
to find the perimeter , you have to add all 4 sides of the shape . if the perimeter is 100 therefore you can divide 100 by 4 and get 25 . If all sides are 25 cm , then the area would be 25 x 25
Let me know if this helps!
