Answer:7

Step-by-step explanation:distance between E and M forms a diagonal. Thus from the y axis we get a triangle. So using pythagoras theorem we have. EM^2= 5^2 +2^2. EM=\/(5+2)^2. EM=7

Need help asap will give brainly

shutvik [7]

Answer:

3 is 75

4 is 124

5 is 61

Step-by-step explanation:

for number 4 angles 6 and 8 are supplementary so they add up to equal 180

if they said that 6=56 then we we subtract 56 from 180

180-56=124 so angle 8 equals 124

for number 5 angles 3 and 5 are also supplementary so the values combined will ad up to equal 180. If they say that angle 5 is equal to 119 then all we have to do to get the value of angle 3 is subtract 119 from 180

180-119-61 so angle 3 equals 61

hope this helps :D
