Answer:
2/1
Step-by-step explanation:
Slope = 2
up 2, right 1
rise over run
×=y/3-z/3+3 thats the x value in this equation
Answer:
6
/5
Step-by-step explanation:
since triangles are similar
4/x = 7x/7
=》 4/x = x
=》x^2 = 4
=》 x = 2
for right triangles a^2 = b^2+c^2
DF^2 = 7^2+2^2 = 53
=》 DF = 7.28
perimeter of DEF = 7 +2+7.28 = 16.28
