Answer:
no it can't because
Step-by-step explanation:
coz the sum of any two angle should be greater than 3rd side
- 13 + 5 = 18 which is greater than 7
- 13 + 7 = 20 which is greater than 5
- 5 + 7 = 12 which is not greater than 13
so triangle cant be made
A and B Definitely. 3 and 17, -3 and -17
Answer:
x = .5
Step-by-step explanation:
4 / x = 8
4 / .5 = 8
x = .5
Answer:
C
Step-by-step explanation:
∠ AFD = ∠ AFB + ∠ BFC + ∠ CFD
The 3 angles form a straight angle and sum to 180°, that is
4x + 5 + 6x + 3 + 5x + 7 = 180, that is
15x + 15 = 180 ( subtract 15 from both sides )
15x = 165 ( divide both sides by 15 )
x = 11
∠ CFD = 5x + 7 = 5(11) + 7 = 55 + 7 = 62°, thus
∠ AFE = ∠ CFD = 62° ( vertical angles are congruent )
