Answer:
Step-by-step explanation:
both angles must add up to 180 so
6x+12+3x+63 must =180
= 9x+75
9x+75=180
-75 -75
9x=105
x=11.66
meaning A is approximately 81.96
Answer:
-x^2+15y-15
Answer if it is a ^2
Step-by-step explanation:
2x^2 + 6y - 3 -(3x^2 - 9y + 12)=
2x^2+6y-3-3x^2+9y-12=
-x^2+15y-15
is it a ^2 or a question mark
It is B because I had the question before in my school
The Correct option is -4
because every other terms result in value = 4, where's -4 is the only different one hence doesn't belongs yo other three
Since you have the 42-deg angle and the length of the opposite side, 31, you can use the Law of Sines.
We will use the law of sines first to find x.
Once we know x, we can find the angle opposite y.
Then we can find y.
Let z = the angle opposite y.
z + 42 + 53 = 180
z = 85
