Answer:
Only area of PQR can be calculated.
Step-by-step explanation:
In PQR, we have both the base (24 cm) and the height (15cm) which is perpendicular to the base. Therefore using these two measurements, we can take
This is equal to 180 cm².
cos^-1(6/13)=62.5136°
sin(2*62.5136°)=0.8189
cos(2*62.5136°)=-0.5740
3/20*100=15 so 15% is answer
47420
nope
71°
95° + 14° = 109°
180° in a triangle
180° - 109° = 3rd angle = 71 °
