i just did this one it is d
Answer:
84
Step-by-step explanation:
Since we are given line OP perpendicular to line DR, then angles PDR and ODR are right angles.
Angles PDA and ADR are complementary.
Angles ODU and UDR are complementary.
Angles ADR and UDR are given as congruent.
We can conclude that angles PDA and ODU are congruent.
By AA Similarity, triangles APD and UMD are similar.
DP/DM = PA/MU
3.75/10 = 4.5/MU
3.75MU = 10 × 4.5
MU = 12 (altitude of triangle DUO)
OD = OM + MD = 4 + 10 = 14 (base of triangle DUO)
area = base × height / 2
area = 14 × 12 / 2
area = 84
1.3 x 10^1
hope that helped
let me know if i am right please
Volume of pyramid = 1/3 lwh = 1/3 Bh
volume of prism = Bh
So volume of pyramid = 1/3 volume of prism
Answer:
first box: one-third
second box: V = 1/3Bh
