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!

In the triangle below, the value of a is 12.6. True False

Answer:

True

Step-by-step explanation:

Formula

Tan(x) = opposite / adjacent

Givens

x = 42

adjacent = 14

opposite = ?

Solution

Tan(42) = opp/14 Find tan(42)

Tan(42) = 0.900404

0.900404 = opp/ 14 Multiply both sides by 14

14 * 0.900404 = opp/14 * 14 Simplify the left

12.6 rounded = opp

a = 12.6

Which is the completely factored form of 3xsquared -12x-15?

tekilochka [14]

Answer:

3(x - 5)(x + 1).

Step-by-step explanation:

3x^2 - 12x - 15

Dividing through by 3:

= 3(x^2 - 4x - 5)

We need 2 numbers whose sum is -4 and whose product = -5. That is -5 and +1 , so the factors are:

3(x - 5)(x + 1).
