triangle B. because congruent is supposed to be the same shape same size but triangle b is same shape but a different size
Answer:
∠1 = 52
∠2 = 128
∠4 = 128
Step-by-step explanation:
∠3 and ∠1 are vertical angles
As we now vertical angles are congruent
So if ∠3 = 52°, then ∠1 also equals 52°
∠3 and ∠4 are supplementary angles
supplementary angles add up to equal 180
Thus, ∠3 + ∠4 = 180
If ∠3 = 52°
Then 52 + ∠4 = 180
180 - 52 = 128
Hence, ∠4 = 128
∠4 and ∠2 are vertical angles
Like stated previously vertical angles are congruent
So if ∠4 = 128 then ∠2 also equals 128
First, find the difference between the original price and the reduced price;
65 - 45 = $20 difference
Then, divide the difference by the original amount;
20/65 ≈ 0.3077
Then, multiply this by 100 to convert the decimal into a percentage;
0.3077 * 100 = 30.77%
The percent of change would be about 30.77%
Answer:
(a) 8
(b) 16
(c) 24
(d) The ratios are the same
Step-by-step explanation:
(a) For inputs -5 and -4, the difference of outputs is ...
-3 -(-11) = 8
__
(b) For inputs 0 and 2, the difference of outputs is ...
45 -29 = 16
__
(c) For inputs -3 and 0, the difference of outputs is ...
29 -5 = 24
__
(d) The ratios of output difference over input difference are ...
8/1 = 16/2 = 24/3 = 8 . . . . . they are all the same
This is yet another confirmation that the slope of a line is the same everywhere, and over any interval.
