Answer:

x = 29

Step-by-step explanation:

Given that both triangles are congruent to each other, therefore, their corresponding angles are congruent as well. This means all three angles in one is the same as all three corresponding angles of the other.

Therefore:

m<CAB = m<CDE = 74°

m<ABC = 2x (given)

m<BCA = 48° (given)

Thus:

m<CAB + m<ABC + m<BCA = 180° (sum of triangle)

Substitute

74 + 2x + 48 = 180

Add like terms

2x + 122 = 180

2x + 122 - 122 = 180 - 122

2x = 58

2x/2 = 58/2

x = 29

Answer:

$2x\sqrt{10}-2x\sqrt 5$

Step-by-step explanation:

$\sqrt{5x} (\sqrt{8x^2}-2\sqrt{x})\\\mathrm{Multiply \: parentheses \: by \sqrt{5x}}\\=\sqrt{5x \times 8x^2}-2\sqrt{5x \times x}\\=x\sqrt {4\times 10 x}-2x\sqrt{5}\\=2x\sqrt{10}-2x\sqrt{5}$

Answer correctly and get brainliset

The answer is the mean is 8. The range is equal to the largest number, 10 minus the smallest number, 5. It equals 5, so d is wrong. The mean is all of the values added together, 80, divided by the number of values, 10. So, 8. The median is the middle which is between 7 and 8, so 7.5. Five has no dots.
