Given. 21 and 2 are complements,
22 and 23 are complements and mzt 35°
Prove m23 35°

Step-by-step explanation:

By the congruent complements theorem , we know that angle 1 is congruent to angle 3. The measure of angle 1 equals the measure of angle 3 by the definition of congruent  angles. Then, using the substitution property, the measure of angle 3 is 35 degrees.

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°
