Find the measure of angle AOB
2 answers:
Answer:
101°
Step-by-step explanation:
20 + 25 = 45
3+2 = 5
5x + 45 = 180
Subtract 45 from 45 and 180 (both sides)
5x = 135
Divide 5x and 135 (both sides) by 5, to finally get..
x=27
3 x 27 + 20 = 101
2 x 27 + 25 = 79
Angle B.O.C = 79
Angle A.O.B = 101

Answer:
U₂₁ and U₂₂ fits in the line of upper triangular
Step-by-step explanation:
As explain in the question
An upper triangular matric is square matrix with all zeros below its daignal. A lower triangular matrix is a square matrix with all zeros above its diagonal.
(as shown in the attached image)
(a)for all 3×3 upper triangular matirices U, verify that U2 is also upper triangular
for a matrices U (having a 3*3 matrix), assuming for example, U is given below:
U =
the element in the upper triangular are 1,2,3,5,6,9 (U₁₁, U₁₂, U₁₃; , U₂₂, U₂₃, U₂₂)
while lower triangular are 0,0,0, the element in the lower triangular are (U₂₁, U₃₁,U₃₂)
U₂₁ and U₂₂ fits in the line of upper triangular
