Answer:

Step-by-step explanation:

If the ratio of triangle = 3:5:7

Total ratio = 3+5+7 = 15

The sum of angle in a triangle is 180°

1st angle= 3/15× 180 = 3 × 12 = 36°

2nd angle= 5/15 × 180 = 5 × 12 = 60°

3rd angle= 7/15 × 180 = 7 × 12 = 84°

Solve for x. (x−2)^2+2=38 x= ___ or x= ___

Elan Coil [88]

Answer:

$x \: = \: \boxed{ \bold{ - 4 }}\: \: \text{or} \: \: x \: = \: \boxed{ \bold{ 8}}$

Step-by-step explanation:

$(x \: - \: 2 {)}^{2} \: + \: 2 \: = \: 38$

${x}^{2} \: - \: 4x \: + \: 4 \: + \: 2 \: = \: 38$

${x}^{2} \: - \: 4x \: + \: 6 \: = \: 38$

${x}^{2} \: - \: 4x \: + \: 6 \: - \: 38 \: = \: 0$

${x}^{2} \: + \: 4x \: - \: 8x \: - \: 32 \: = \: 0$

$x \: \times \: (x \: + \: 4) \: - \: 8(x \: + \: 4) \: = \: 0$

$(x \: + \: 4) \: \times \: (x \: - \: 8) \: = \: 0$

When it happens that the product of the factors is the same as zero. It is divided into two possible cases.

$x \: + \: 4 \: = \: 0 \\ x \: - \: 8 \: = \: 0$

We solve the two equations:

$x \: = \: - 4 \\ x \: = \: 8$

<h2>Answer: </h2>

$x \: = \: - 4 \\ x \: = \: 8$
