\sf\purple{The\:value\:of\:x\:is\:10.4.}✅

<u>Step</u>-<u>by</u>-<u>step</u> <u>explanation</u>:

\frac{(10x - 4)}{5}  = 20 \\ ✒ \: 10x - 4 = 20 \times 5 \\ ✒ \: 10x = 100 + 4 \\ ✒10x = 104 \\ ✒ \: x =  \frac{104}{10}  \\ ✒ \: x = 10.4

\sf\red{Therefore,\:the\:value\:of\:x\:is\:10.4.}

<u>To </u><u>verify</u>:-

\frac{(10x - 4)}{5}  = 20 \\ ✒ \:  \frac{10 \times 10.4 - 4}{5}  = 20 \\ ✒ \:  \frac{104 - 4}{5}  = 20 \\ ✒ \:  \frac{100}{5}  = 20 \\ ✒ \: 20 = 20 \\ ✒ \: L.H.S.=R. H. S

Hence verified. ✔

From the given sides of 16, 14, and 21, determine what type of triangle it will form (right, acute, obtuse, none).
Komok [63]

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.
