Step-by-step explanation:
<u>Subquestion #1</u>
- These angles form a linear pair
- They are supplementary, and add up to 180°
- 2x + 48 = 180
- 2x = 132
- <u>x = 66</u>
<u></u>
<u>Subquestion #2</u>
- These angles are complementary, and add up to 90°
- 35 + 4x + 7 = 90
- 4x + 42 = 90
- 4x = 48
- <u>x = 12</u>
<u></u>
<u>Subquestion #3</u>
- As in #1, they are a linear pair, and are supplementary
- 3x + 54 = 180
- 3x = 126
- <u>x = 42</u>
For this case we have that by definition, it is called arcsine (arcsin) from a number to the angle that has that number as its sine.
We must find the
. Then, we look for the angle whose sine is
.
We have to, by definition:

So, we have to:

Answer:
Option B
Nine is in the tenths place
Answer:
Step 1: 3*4=12
Step 2: 12+3=15
Step 3: 15-10=5
Step-by-step explanation:
Statements Reasons
1.) M is the midpoint of CD; CM = 5x – 2; MD = 3x + 2 1.) Given
2.) CM=MD 2.) Definition of midpoint
3.) 5x-2=3x+2 3.) Substitution
4.) 2x-2=2 4.) Subtraction Property of Equality
5.) 2x=4 5.) Subtraction Property of Equality
