Equal to a+b on the algebra
if 3/4 of the grapes are green, than 1/4 are purple.
5/8*1/4=5/32
5/32 *1/10= 1/64
Each friend gets 1/64th of a pound of grapes
Answer:
c = b/cos 45
Step-by-step explanation:
SOHCAHTOA
- We use Cos
- Cos 45 = b/c
- c = b/cos 45
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.
A & b would be the congruent pair of angles
