Volume of prism= (Area of the trangle)*lenght
Area of the Triangle= (b*h)/2=7 ft *5 ft /2=35 ft /2=17.5 ft²
lenght is 8 ft
Volume= 17.5 ft² * 8 ft = 140 ft³
Answer:
20
Step-by-step explanation:
1) NPM, MPQ and QPR are supplementary angles, meaning that they touch each other, and add up to 180 degrees.
NPM + MPQ + QPR = 180
2) NPM = 70, MPQ = 90
3) QPR = 180 - 90 - 70 = 20
QPR = 20
