Answer:
PV=20 QU=15 VS=26
Step-by-step explanation:
From what I understand, the line that crosses the centroid is normally separated into 3rds.
For example: QU is the full length, 3/3, and QV is 2/3 of QU. and VU is 1/3 of QU. If we know that QV is 10 then that means that 2/3 of that legment is 10.
10÷2=5
So, 5 would be 1/3 of QU. To find QU(3/3), you would need to multiply 5 by 3 which is 15.
Same thing applies for the other ones.
I hope this makes sense and helps you!
0.625 would be 5/8 as a decimal
Answer:
10.5??
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Using the cofunction identity
sin x = cos(90 - x)
Given
sin(3x + 19) = cos(5x - 25), then
3x + 19 = 90 - (5x - 25)
3x + 19 = 90 - 5x + 25
3x + 19 = 115 - 5x ( add 5x to both sides )
8x + 19 = 115 ( subtract 19 from both sides )
8x = 96 ( divide both sides by 8 )
x = 12 → B
