Answer:
sinA = ± 
Step-by-step explanation:
Using the Pythagorean identity
sin²A + cos²A = 1 ( subtract cos²A from both sides )
sin²A = 1 - cos²A ( take the square root of both sides )
sinA = ±
Answer:
look below
Step-by-step explanation:
To round a number to the nearest tenth , look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
Answer:
x = −1/13 and y = 33/13 or 2 7/13
Step-by-step explanation:
x+2y=5
x+2(6x+3)=5
x+12x+6=5
13x+6=5
-6 -6
13x= -1
/13 /13
<u>x= -1/13</u>
y=6x+3
y=6(-1/13)+3
y= 33/13
y= 2 7/13
