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
Answer:
Volume of the rectangular prism = 2366 cubic inches
Explanations:
The volume of a prism = Base Area x Height
In this case, the base area is referred to as the face area
Base area = 169 square inches
Height = 14 inches
Volume of the prism = 169 x 14
Volume of the rectangular prism = 2366 cubic inches
Answer:
6.9 I think.
Step-by-step explanation:
Answer:
∠K =24
∠L =66
Step-by-step explanation:
first you need to find X in order to solve.
since they are Complementary they add together to equal 90 degrees
so we can set them equal to 90
13x-1=90
13x=91
x=7
now we can plug them in!
---
∠K = 3(7)+3 = 24
∠L =10(7)-4=66
50,000 ÷ 250 = 200
This means that there are 200 seats in each section.
