Answer:
90 cubic inches
Step-by-step explanation:
V = 1/3 · area of base · height
V = 1/3 · 18 · 15
V = 6 · 15
V = 90
Yes because it's a improper fraction
∠LQK+∠GQL=90º
Therefore:
(4n-15)+(3n)=90
7n=90+15
7n=105
n=105/7
n=15
∠LQK=4n-15=4(15)-15=60-15=45
Answer: ∠LQK=45º
Answer:
on example 1, both are right triangles.
