Answer: B = 56 degrees
Step-by-step explanation: Complementary angles add up 90 degrees. So we will set both of the equations equal to 90 degrees and then solve from there.
6x+8+5x+21=90
1. Simplify 5x + 6x and 21 - 8
11x+13=90
2. Subtract 13 from both sides.
11x=90-13
3. Simplify 90-13 to 77.
11x=77
4. Divide both sides by 11.
x = 77/11
5. Simplify 77/11 to 7
x=7
Now we have to take the value of x and substitute it back into B = (5x+21)
1. Substitute
B = (5(7)+21)
B = 35 +21
B = 56

Answer:
<em>The answer is 24</em>
Step-by-step explanation:
The given triomino follows as sequence that,
<em>The upper no. × The right no. -The left no. = The middle no </em>
As we can see this by analyzing the three triominoes
first triominoes
4 × 2 - 4 =4
second triominoes
6×1 - 5 = 1
third triominoes
3×4 -0 = 12
∵ Finding fourth triominoes
9×3 - 3 = 24
<em> </em><em> ∴ The answer is 24</em>

Answer: £460
Step-by-step explanation:
Use this formula to find the total interest 
I stands for interest, P is principal, R is rate, and T is time.
Principle = £2300
Rate = 5%
Time = 4 years

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)
