If E is the midpoint, DE and EF are equivalent.
2x+4=3x-1
4=x-1
5=x
Plug the value of x in
2(5)+4
14
3(5)-1
14
14+14=28
Final answer: DE=14, EF=14, DF= 28
Start with an equation summing all the angles in this triangle:
180 = <M + <N + <P
we are given <M and <N but not <P. But, since MN=NP, the angle <P is the same as the angle <M (isosceles, make a drawing to see). So
180 = 2<M + <N
180 = 2(3x+1) + x-11
180 = 7x - 9
x = 27
<P = 3*27+1 = 82 degrees
Yes, set up your proportion: x/21 = 10/14
Cross multiply 14x = 210
Divide both sides by 14 and x= 15 cm
Answer:
h
Step-by-step explanation:
square root of 260 is 16.1 therefore h is the closest
