Answer:
Step-by-step explanation:
Given ∆DEF,
<F = 36°
DF = e = 15
EF = d = 6
DE = f = ?
f can be found using the Law of Cosine as shown below:
Plug in your values:
Evaluate:
(to nearest tenth)
Answer:
True
Step-by-step explanation:
Because the bottom and top parts are not congruent but the sides are.
Answer:
x=30
Step-by-step explanation:
(x-1)+151=180
(x-1)=29
x=30
You would just do like 60 and 3 for example. Then you keep breaking 60 down into 30 and 2, then 15 and 2, and then 3 and 5, and that would be your final answer. Multiplying all those prime factors gives you 180. The answer would be 3*2*2*3*5. Hope this helps. Please rate, leave a thanks, and mark a brainliest (Not necessarily mine).

Answer:
x=4, y=13. (4, 13).
Step-by-step explanation:
3x+2y=38
-6x+4y=28
----------------
simplify -6x+4y=28 into -3x+2y=14
-------------------------------------------------
3x+2y=38
-3x+2y=14
------------------
4y=52
y=52/4=13
3x+2(13)=38
3x+26=38
3x=38-26
3x=12
x=12/3=4
x=4, y=13.
