Answer 1

Ответ:

hв= 8,5

Объяснение:

ha = 7 a=5

7:2=3,5

3,5+5=8,5

ответ : 8,5

Answer 2

Task: Finding the height of a triangle

To find the height of a triangle, we need to know the lengths of two sides and the length of the corresponding altitude. In this case, we are given that the sides of the triangle are a = 5 and b = 12, and the corresponding altitude is ha = 7. We need to find the height hb.

To solve this problem, we can use the formula for the area of a triangle:

Area = (base * height) / 2

Since we know the lengths of two sides and the corresponding altitudes, we can calculate the area of the triangle using two different formulas:

Area = (a * ha) / 2

Area = (b * hb) / 2

Since the area of the triangle is the same in both cases, we can equate the two formulas and solve for hb:

Area = (a * ha) / 2 = (b * hb) / 2

Now let's substitute the given values into the equation and solve for hb:

Area = (5 * 7) / 2 = (12 * hb) / 2

Simplifying the equation:

35 = 6 * hb

Dividing both sides by 6:

hb = 35 / 6

Therefore, the height of the triangle, hb, is approximately 5.83.

Please note that the above calculation assumes that the given values are accurate and the triangle is a right triangle. If the triangle is not a right triangle or the given values are incorrect, the result may be different.

I hope this helps! Let me know if you have any further questions.
