Since the angle to the right of the angle are vertical angles with 41 it is safe to assume that the one next to it is also 41. So you add 56+41 and then set it equal to 180. 56+41+X =180 So you get 97+X=180 and then you subtract 180-97=X so X =83. And you can double check this by plugging it in to the equation.

97+X(83)=180

1. The structure of the supports for the hill consists of steel beams that

Darina [25.2K]

a) Parallel for both line segments have the same slope = -5/4

b) 55º

Step-by-step explanation:

a) To verify the parallelism of these line segments, It's necessary to find the slope of each one. Parallel lines share the same slope value:

$m_{BC}=\frac{0-150}{120-0}=-\frac{-5}{4}\\m_{AD}=\frac{0-125}{100-0}=-\frac{5}{4}$

b) If ∠DAB = 125°, what is the measure of ∠CBA? Justify your reasoning.

Those beams do not form a parallelogram because:

Using the formula of distance between those points

$d=\sqrt{(y_{2}-y_1)^{2}-(x_{2}-x_{1})^2$

$\overline {AB}=25\: \: \: \overline{CD}=20\: \: \overline{AD}=160 \: \: \overline{BC}=192$

So this is a trapezoid. And two adjacent angles within a trapezoid are supplementary, so If ∠DAB = 125º then 180 - ∠CBA=55º

True or false? If you took a true "if-then" statement and reversed the clauses, the new statement would also be true

lbvjy [14]

That's false.

Here's a counter-example:

If an animal is a dog, then it has four legs. This is true.
but
If an animal has four legs, then it is a dog. This is not necessarily true.

Another one:

If a shape is a square, then it has four sides. Always true.
but
If a shape has four sides, then it is a square. Usually not true.
