15 in, 4 in, 20 in
Step-by-step explanation:
The sum of the smaller two sides of a triangle must be greater than the third side.
Hello,
1/4 + 4 = 1/4 + 16/4 = 17/4
Bye ;)
For all of these answers, the equation used was (AB + CD)/2 = EF
1.12+24=36 36/2=18
2. 21 + 35 = 56 56/2 = 28
3. (7 + EF)/2 = 9
multiply by 2
7 + EF = 18
subtract 7
EF = 11
4. (AB + 32)/2 = 22
Multiply by 2
AB + 32 = 44
Subract 32
AB = 12
5. Average
Answer:
m<BEC = 40o
Step-by-step explanation:

y - y₁ = m(x - x₁)
y - 2 = -1¹/₄(x - 5)
y - 2 = -1¹/₄(x) + 1¹/₄(5)
y - 2 = -1¹/₄x + 6¹/₄
+ 2 + 2
y = -1¹/₄x + 8¹/₄
