< BAC = 50
< BCA = 90
interior angles of a triangle add up to 180
so < ABC = 180 - (90 + 50) = 180 - 140 = 40
and < ABC = < CDE.......so < CDE = 40 <===
Answer: 107
Steps: add 12 + 106
= 118
subtract 332 - 118
= 214
divide 214/2
= 107
Answer:
The total number of possible outcomes if the code has 3 letters is 64
Step-by-step explanation:
The keypad has only the letters A-D, that is, A,B,C,D.
To calculate the total number of possible outcomes if the code has 3 letters,
let these spaces represent the code _ _ _
For the first space, there are 4 possibilities (since we have 4 letters)
For the second space, we also have 4 possibilities (since there is no restriction on repetition)
Also, we have 4 possibilities for the last space.
Hence, the total number of possible outcomes if the code has 3 letters is 4×4×4 = 4³ = 64.
Perpendicular slopes are opposite reciprocals.
This means the slope of the line perpendicular to GA will be the opposite reciprocal of -5.
Reciprocal of -5: -1/5
Opposite of -1/5: 1/5
The slope of the line perpendicular to GA is 1/5.
