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.

Step-by-step explanation:
Answer:
378+567-142÷5= 916.6
456(325-541)÷32= -3078
Step-by-step explanation:
Answer:
No, is 0.675
Step-by-step explanation:
First, you subtract 16r by 9r, which gives you 7r, so that leaves you with 8 + 7r. You cannot add a normal number and a number with a variable, so that's all you can do, so your answer is A.
