**Answer:**

V=-11

**Step-by-step explanation:**

V + 6/2 = -8

You simplify the 6/2 <em>PEMDAS</em>

V + 3 = -8

You subtract 3 from both sides <em>PEMDAS/isolate the variable/combine like terms</em>

V = -11

**Answer:**

add them up

**Step-by-step explanation:**

add 8 10 10 and 80 25 20

**Answer:**

if ∠Q=∠R

draw an angular bisector from P to QR in which it intersect wit Qr at point S

now we have two triangle : QPS and RSP

in which angle : QPS=RPS ( PS is angular bisector)

and we have angle Q and angle R are equal

and PS is common side

this makes triangle QPS and RSP are congruent by AAS(angle angle side)

which also means that pQ=PR ( proved)

**Answer:**

The solution is X=7.4 sin38°
