Answer:
A right prism is a prism that has its bases perpendicular to its lateral surfaces.
When we cut a prism parallel to the base we get a cross section of a prism. The cross section is congruent (same size and shape) as the base, as can be seen in the following diagram.
√145 cm
Step-by-step explanation:
By Pythagoras property
Hypotenuse² = base²+perpendicular ²
(AC)² +(BC)² =(AB)²
9² + 8² = (AB)²
81+64 = (AB)²
145 =(AB)²
AB =√145

Answer:
134.5 degree
Step-by-step explanation:
first find the remaining side of a triangle
BY using cosine rule
C^2=A^2+B^2-2ABcosx
apply square root both sides
√c^2 =√[4^2+10^2-2(4)(10)cos29]
C=√(116-69.96958)
C=√46.03
C=6.8
Now find angle using cosine rule
C^2=A^2+B^2-2ABcosx
10^2=4^2+6.78^2-2(4)(6.78)cosx
100=16+45.9684-54.24cosx
100=61.9684-54.24cosx
100-61.9684=-54.24cosx
(38.0316)/-54.24=(-54.4cosx)/-54.24
-0.70117=cosx
X= cos inverse of -0.70117
x=134.5 degree
x=-7
put them next to each other and solve.
