The degree is 0. I don't know how to solve it I just used a website that allows you to answer things like this. <span />
Take 49 and divide it by 7 and you get 7. 7 times 10 is 70. Your answer is $70.
Answer:
EF = 58/7
Step-by-step explanation:
If you extend both BC and AD to meet at P you get 3 similar triangles PAB, PEF, and PCD. Let's call BF = 3x and FC = 4x. Therefore the following proportions can be expressed:
BP/7 = (BP+7x)/10
10BP = 7*(BP+7x)
10BP = 7BP+49x
3BP = 49x
BP = (49/3)x
BP/7 = (BP+3x)/EF
EF = (BP+3x)*7/BP
EF = ((49/3)x + 3x)*7/((49/3)x)
EF = ((58/3)x*7*3)/(49x)
EF = 58/7
I know it's either A B C or D.
You didn’t show us the answers we can choose, how do we solve it then
