You should have a theorem that says that a midsegment between two sides is parallel to and half the length of the third side.
<span>Since DF is a midsegment = 17, then AC will be 17*2 = 34 </span>
<span>The fact that EC = 30 is extra information, given to throw you off (it worked on me for a bit)</span>
Answer:
The number is 59/5 or 11.8 (decimal)
Step-by-step explanation:
This sentence can be written as 5(x-6)=29
x-6 = 29/5
x = 29/5 + 6
x = 59/5 or x = 11.8
All you have to do is subtract them. 313-178=135
Answer:
y ≈ 12.3
Step-by-step explanation:
Using the SOH CAH TOA identity to get the value of y as shown;
sin theta = opposite/hypotenuse
opposite = y
hypotenuse = 15cm
theta = 180-(35+90)
theta = 180-125
theta = 55 degrees
sin 55 = y/15
y = 15sin55
y = 12.287
y ≈ 12.3 (to the nearest tenth)
