65 x 4 = 260 cm was left after tying the parcel
260 + 45 = 305 cm was the total length
The area is 115.5
I did this by subtracting 7 (from the triangle) from 20 to find the the rectangle width!
20-7= 13
Area of rectangle
13•7 =91
Area of triangle
(7•7)/2= 24.5
But it asked the area of the figure so you’ll add both of them together
24.5 + 91 = 115.5
I guess you are talking about a triangle . The 3 angles add up to 180 degrees.
b + c = 180 - 25 = 155 degrees
When b > 51 degrees then
c <= 155 - 52
c <= 103 degrees
When b < 57
c >= 155 - 56
c >= 99 degrees
Possible measurements for angle c :=
99 =< c <= 103 (answer).
Answer:
1.) 17.15
2.)112
3.)99
I think these are right
