For the given figure, x = 34.640 units.

Step-by-step explanation:

Step 1:

The formulae needed to solve this question are:

The triangle containing x can be split into two right-angled triangles.

So the hypotenuse of the triangle containing the length x and the already given right angle triangle's hypotenuse is the same length.

Step 2:

First, we calculate the hypotenuse of the given triangle.

The angle of the triangle is 45°, the adjacent side's length = 10√3 units. Assume the hypotenuse's length to be a units.

units.

Step 3:

For the split triangle, we have the angle as 45°, the opposite side measuring units (only half of x is in each triangle) and the hypotenuse measuring 24.498 units.

So x measures 34.640 units.

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
