<h3>Yes, this is true.</h3>
To be considered similar triangles, the angles must be the exact same, and the sides must be proportional. The side lengths do not have to be exactly the same, but they must be proportional (like a ratio, suppose one triangle has a side length of 1, and the similar triangle has a side length of 3. The ratio is 1:3, and all sides will follow this ratio.)
Answer:
angle 4 = 34 degrees
Step-by-step explanation:
angle 4 is equal to angle 2 because it is an alternate interior angle of 34 degrees.
5/11
11 goes into 5 zero times (0.)
11 goes into 50 four times with a remainder of 6 (0.4)
11 goes into 60 five times with a remainder of 5 (0.45)
11 goes into 50 four times with a remainder of 6 (0.454)
11 goes into 60 five times with a remainder of 5 (0.4545)
The answer is .45 with a bar on top of both the 4 and the 5.
The scale factor of the Reba's drawing is 9/84, 3/28
Step-by-step explanation:
The scale factor is the ratio between the two corresponding sides of the figure. The point worth noting in computing the scale factor is that both sides must have similar units of dimension while using for comparison purpose.
Given the scale used by Reba is 9 inches to 7 feet
Since both the units are different, we have the option to either convert inches to feet or vice versa
We proceed with converting feet to inches
We know that 1 foot equals to 12 inches. Hence 7 feet would equal 84 inches.
Now scale factor= first dimension/ corresponding dimension
Scale factor= 9/84 which can be reduced to 3/28
Given:
The function is
To find:
The value of f(-1).
Solution:
We have,
Putting x=-1, we get
Therefore, the value of f(-1) is -12.
