Let's call the missing angles Q, R, and S. We know that Q = 2R and S = R - 8 and we also know that Q + R + S = 180. So that really just means that 180 = 4R - 8 Add 8 on both sides of the equal sign
188 = 4R So we divide on both sides of the equal sign by 4
47 = R And that means that Q = 2 * 47 So Q = 94 and S = 47 - 8 So S = 39
39 + 94 + 47 = 180
The missing angles are 39 degrees 94 degrees and 47 degrees.
Hello,
In order to be simple: let's code hexadecimal numbers on 4 digits.
Example: 500-200=300 (in décimal)
She has enough money, the total will be $95
you add 10+10+75, to get $95
Answer:
x ≈ 95.6
Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationship between trig functions and sides of a right triangle. Here, the hypotenuse of the triangle and the side adjacent to the given angle are marked, so the relationship of choice is ...
Cos = Adjacent/Hypotenuse
__
Using the values shown, we have ...
cos(15°) = x/99
Solving for x gives ...
x = 99·cos(15°) ≈ 95.6
The length of the side marked x is about 95.6 units.
