There are TWO angles, if one angles is x then the other angle is 2x, lets set up an equation. The equation is going to be x+2x=90. Now we solve, x=1x, so 1x+2x=3x. 3x=90. Divide both sides by 3, 3x/3=90/3, 90/3=30, x=30. Add 30 by 30, 30+30=60. So, the answer is b) 60°

Two complementary angles must add to 90 degrees, and if you divide 90 into thirds (two parts for the larger angle, one for the smaller), then you get 30 degrees.

If the smaller angle is 30 degrees, then the larger is two times that, which is 60. 60 + 30 = 90, so the larger angle is equal to 60 degrees.

Brian irons 2/9 of his shirt in 3 3/5 minutes. At this rate, how much of his shirt does he iron each minute?

vodka [1.7K]

The speed for which Brian iron the shirts is given by:

$R = \frac{\frac{2}{9}}{3\frac{3}{5}}$

Rewriting we have:

$R = \frac{\frac{2}{9}}{\frac{18}{5}}$

$R = \frac{10}{162}$

Then, for each minute, we have the amount of ironed shirt is:

$(\frac{10}{162})(1) = \frac{10}{162}$

Answer:

At this rate, Brian plans 10/162 of his shirt.

XYZ is a dilation of triangle ABC by a scale factor of 5. Which of the following proportions verified that triangle ABC and XYZ

Dima020 [189]

Answer:

C. AB/XY = AC/XZ

Step-by-step explanation:

Dilation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. The original figure either stretches or shrinks by a certain factor.

In the problem, the dilation is by a factor of 5 and we can see that ABC shrinks to form XYZ.

So, ABC and XYZ are similar triangles which means that the ratio of their corresponding sides will be equal:

AB/XY = AC/XZ = BC/YZ = 5
