Answer:
x = sqrt(39)
Step-by-step explanation:
Let y = common side of the two triangles.
Upper right triangle:
6^2 + y^2 = 10^2
y^2 = 100 - 36
y^2 = 64
y = 8
Lower left triangle:
5^2 + x^2 = 8^2
x^2 = 64 - 25
x^2 = 39
x = sqrt(39)
Answer:
?
Step-by-step explanation:
Ok so their are 36 people that didn't need gel for there hair. so when you multiply 36 x 5 (because each cut costs 5 bucks) you get an answer of 180. so hold on to that and since their are 16 people that asked for gel you would need to first multiply 5 and 10% which gives you 0.5 so when you multiply 5.5 (because when you multiplied the 10% with the 5 you should get .5) times 16 you should get an answer of 88. when you add 180 with 88 you get an answer of 268.

Answer:
It is an acute triangle.
Step-by-step explanation:
It would be much easier for you to see where I'm getting at if you draw a diagram.
Assume this triangle is labelled ABC where a = 14, b = 21, and c = 16.
cos A = (16^2 + 21^2 - 14^2)/(2(16)(21))
∠A = cos^-1(0.82291...)
∠A ≅ 34.6°
cos B = 16^2 + 14^2 - 21^2)/(2(16)(14))
∠B = cos^-1(0.024...)
∠B ≅ 56.8°
∠C = 180 - (∠A + ∠B)
∠C ≅ 56.8°
Since there is no right-angle nor is there an obtuse angle,
Therefore the triangle is an acute triangle.
3(2x+4), 6(x+2), and 2(3x+6)
Hope this helps
