Choose which trig ratio to use. - Choose either sin, cos, or tan by determining which side you know and which side you are looking for. - Solve the resulting equation to find the length of the side. Step 1: Choose which trig ratio to use.
1 cm : 15 yd
Multiply this proportion by 5
5 cm : 75 yd
Multiply the original proportion by 8
8 cm : 120 yd
a) The dimensions of the field are 75 yd by 120 yd.
b) The area is (75 yd)*(120 yd) = 9000 yd^2.
Answer:
9 is the real part and 7i is the imaginary part
Step-by-step explanation:
A complex number is written in the form a+bi where a is the real part and bi is the imaginary part
9 = real part
7i is the imaginary part
The answer is A! I asked the same question and that’s the answer I got.
Answer:
x = 11
Step-by-step explanation:
Equation:
(5x+1) + (12x-8) = 180
You are doing this because both sides on a straight line add up to 180 degrees. The two angles would add up to 180 degrees since they are on the one side of the line.
Simplifying:
(5x+12x) + (1-8) = 180
Add your common variables together; keep in mind that variables are placed before numbers.
Adding:
17x-7 = 180
Process:
To do this, you are going to simply do the opposite operation for the number without the variable on both sides of the equal sign.
17x - 7 = 180
+ 7 + 7
------------------
17x = 187
----- ------
17 17
x = 11
You divided by 17 on both sides because you needed to get the x variable by itself. Hope this helped! :)
