Answer:

The value of x would be 20

Step-by-step explanation:

To solve this triangle, we need to first note that all triangles have 180 degrees. So we can add these all together and set equal to 180.

40 + 3x + 4x = 180

40 + 7x = 180

7x = 140

x = 20

in a wood there are 420 silver birch trees, 160 oak tees and 300 wild cherry trees. what is the percentage of the oak trees give
elena-14-01-66 [18.8K]

Answer:

18.2%

Step-by-step explanation:

The total number of trees in the wood = 420 + 160 + 300

                                                                = 880 trees

∴ The percentage of the oak trees = \frac{160}{880} * \frac{100}{1}

                                                            = \frac{2 * 100}{11}%

                                                            = \frac{200}{11}%

                                                            = 18.181818...%

In 1 decimal place = 18.2%

Hope this helps!!
