Step-by-step explanation:
Given:
Let B be between A and C.
To Find:
x=?
Solution:
B be between A and C as shown in Figure
A-B-C such that
...........Line Addition Property
Substituting the given values we get

The value of x is 4.
So 3x3 is equal to 9 but i do not understand what you mean and multiply to 16
Answer:
x = 16.6
Step-by-step explanation:
Since we know the measure of an acute angle (31 degrees) of a right angle triangle, and of the side opposite to the angle (10), and we need to find the measure of the adjacent side "x", we use the tangent function:

which rounded to one decimal is
x = 16.6
B. 31°, 43°, 106°
since all angles of a triangle add up to 180°, you combine all of the equations to equal 180 and solve for X. the equation you would get it 3x+1+11x-4+5x-7=180. this simplifies to 19x-10=180. then you solve for x, and it is 10. then, you plug 10 into all of the equations separately to find the angles. therefore, the answer is B
