Trig please help.
Finding the area of similar right triangles whose scale factor is 3:1.
The first angle ABC shown has a base of 6 and a height of 9. Longest side 12.
The second angle PQR has a base of 3 and a height of 9. The longest side 9.

10

step-by-step explanation:

7+3=10

26 is 33.33% of 78

step-by-step explanation:

26 is what percent of 78?

26 is p% of 78

equation: y = p% * x

solving our equation for p

p% = y/x

p% = 26/78

p = 0.3333

convert decimal to percent:

p% = 0.3333 * 100 = 33.33%

38.6°

step-by-step explanation:

resultant is 10 pound

smaller force = 8 pound

angle formed = tan⁻¹(

                        =tan⁻¹(

                          =tan⁻¹(0.8)

                        =38.6°

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
