Answer:
He'll have $195 left
Step-by-step explanation:
$35 x 3 = $105
$300 - $105 = $195
Answer:
- Two unique triangles possible
Step-by-step explanation:
Given two sides of 10 cm and one 40° angle
<u>If we use these, we'll get isosceles triangle with:</u>
1. Included 40° angle.
<u>Then the other angles will be same and measure:</u>
2. Adjacent 40° angle. Then one of the angles must be 40° angle as opposite of 10 cm sides.
<u>The remaining angle will measure:</u>
There no more unique triangles possible, so the answer is two.
Answer: B) Dilate by scale factor of 2
====================================================
Explanation:
Your teacher isn't saying this directly, but I'm assuming s/he wants you to find a similar figure that isn't congruent to the original. Informally, your teacher seems to want you to find a figure that is the same shape but not the same size as the original.
If so, then any dilation will shrink or enlarge the image depending on the scale factor. So the new image will not be the same as the old one. In this case, a dilation with scale factor 2 means the new figure is twice as large (each side is twice as long). But the old image is similar to the new image. The angles keep their values and therefore we get the same shape. This is why choice B is the answer. Again this is assuming what I mentioned in the first paragraph.
Choices A, C, and D are all known as rigid transformations and they preserve the same size of the figure. Applying any of those operations will lead to the same figure (just rotated, reflected or shifted somehow). In other words, applying operations A,C, or D will have us get two congruent triangles. If two triangles are congruent, then they are automatically similar, but not vice versa. This is why we can rule out A,C, and D.
Answer:
it is 20% your welcome
Step-by-step explanation:
because when you divide 100 by 2 its 50 so its 20%
Answer:
<h3>A. C. E. F.</h3><h3>That is, 2, 3, 5 and 6.</h3>
Step-by-step explanation:
In geometry, <em>exterior angles are any angle place between any side of a shape and a line extended from the next side</em>, as the figure shows.
As you can see, angle 2 and 3 are formed by a side of the triangle and an extended line from the next side. Similarly, angles 5 and 6 are formed the same way. Therefore, those four are exterior angles.
