Answer:
QR ≈ 16.2 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan62° = 
= 
= 
( multiply both sides by 8.6 )
8.6 × tan62° = QR , then
QR ≈ 16.2 ft ( to the nearest tenth )
For this you will have to make a tree diagram
it will be so much easier although there is a way to do it
probability of getting heads is = 1/2 there for 10 tosses its (1/20)^10
The surface area 3 times greater than the area.
6 * 2 gives the area
the surface area is by multiplying area by 3.
this means that the surface area is 3x bigger than area.
