Answer:

x = 5

Step-by-step explanation:

These triangles are similar, so they are in proportion to each other. Because of this we can say \frac{2.5}{3.5} (the lengths of the vertical sides) = \frac{x}{7} (the lengths of the hypotenuses). If we solve by cross-multiplying the numbers and then dividing  we get x = 5.

If the ratio of three angles of a triangle is 2:3:4 find the size of the largest angle​
Murljashka [212]
Answer: 80°

Step-by-Step Explanation:

By Angle Sum Property of a Triangle, all angles in a Triangle add up to 180°

Finding the Value of ‘x’ :-

2x + 3x + 4x = 180
5x + 4x = 180
9x = 180
x = 180/9
=> x = 20

Finding each Angle :-

2x = 2(20) = 2 * 20 = 40°
3x = 3(20) = 3 * 20 = 60°
4x = 4(20) = 4 * 20 = 80°

Hence, the Largest Angle is 80°

Multiplying a certain even number by 4 then subtracting 16 gives you the next consecutive even number. Find the original number
anyanavicka [17]

Let 2k represent the original even number (such that k is an integer)

then 2(k + 1) is the next consecutive even number.

4(2k) - 16 = 2(k + 1)

8k - 16 = 2k + 2

6k = 18

k = 3

since 2k represents the original number, then 2(3) = 6 is the oroginal number
