Answer: You can simply use a calculator.
Step-by-step explanation:
<h3>Answer:</h3>
A) ∠A = ∠A' = 38° and ∠B = ∠B' = 42°
<h3>Explanation:</h3>
The sum of angles in ∆ABC is 180°, so ...
... (2x -2) + (2x +2) + (5x) = 180
... 9x = 180
... x = 20
and the angles of ∆ABC are ∠A = 38°, ∠B = 42°, ∠C = 100°.
___
The sum of angles of ∆A'B'C' is 180°, so ...
... (58 -x) +(3x -18) +(120 -x) = 180
... x +160 = 180
... x = 20
and ∠A' = 38°, ∠B' = 42°, ∠C' = 100°.
_____
The values of angle measures of ∆ABC match those of ∆A'B'C', so we can conclude ...
... A) ∠A = ∠A' = 38° and ∠B = ∠B' = 42°
Answer:
c
Step-by-step explanation:
Step 1: calculate the number
everytime the number goes up by 5 so we can assume that it will be 25
step 2: find the letter
it just goes by the alphabet so we can assume it will be e.
the letter always follows the number and it alternates between uppercase and lower case and last time it was uppercase so it will be lowercase.
Therefore it will be 25e
Answer: -25 degrees
Step-by-step explanation:
11. It means below zero on whichever scale is in use or generally understood— centigrade, Delisle, or what have you. It would mean the same as freezing in scales where the freezing point of water is set at zero, such as Celsius or Réaumur, but not in scales where zero is set to something else, as in Leiden or Rømer
Answer:
it should be A, B, D, and E
