Answer:
x = 4
Step-by-step explanation:
<u>All triangles add up to 180 degrees</u>
76 + 17x + 9x = 180
76 + 17x + 9x - 76 = 180 - 76
26x / 26 = 104 / 26
x = 4
Answer: x = 4

Step-by-step explanation:
How can you remember the formula?
Well, it helps to know it's the Pythagoras Theorem with something extra so it works for all triangles:
Pythagoras Theorem:
(only for Right-Angled Triangles) a2 + b2 = c2
Law of Cosines:
(for all triangles) a2 + b2 − 2ab cos(C) = c2
So, to remember it:
think "abc": a2 + b2 = c2,
then a 2nd "abc": 2ab cos(C),
and put them together: a2 + b2 − 2ab cos(C) = c2
Answer:
i think kevin made $7.50 more than clark
Step-by-step explanation:
25% of 50 is 12.5. 50-12.5= 37.5
40% of 50 is 20. 50-20=30
