I'll help you out with 3 questions.
For #1, you kind of figured it out yourself
That 90 degree angle on paper means that m/1 and m/2 make up 90
If m1 is 50, then just subtract m1 (50) from 90, making it 40. m/2 is 40
If Angle M4 is 45 degrees then angle M3 is 180-45 since they both make up a 180 degree angle.
There are 180 degrees in a triangle
If m 8 = 78
and m 9 = 60
m 10 is 180 - 78 - 60
It would change to 3(2+6) and then you would just multiply 3 and 8. the answer is 24.
Answer:
10-5i
Step-by-step explanation:
Conjugate is the change of sign
so I changed the + sign to -
Answer: $1100 will represent the amount after 2 years at the rate of 5%.
Step-by-step explanation:
Since we have given that
Principal amount = $1000
Rate of interest = 5%
Time period = 2 years
As we know the formula for "Simple Interest ":
And we know that
So, $1100 will represent the amount after 2 years at the rate of 5%.

<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
Step-by-step explanation:
<u>Step 1: Define</u>
f(x) = 2x + 5
f(3) is x = 3
<u>Step 2: Solve</u>
- Substitute: f(3) = 2(3) + 5
- Multiply: f(3) = 6 + 5
- Add: f(3) = 11
