Answer:
70 degrees
Step-by-step explanation:
Supplementary means the angles add up to 180 degrees. We can set up an equation using this:
9x+20+6x+10=180
Combine like terms.
15x+30=180
Isolate variable.
15x=150
x=10
Substitute in the variable for the expression of angle B
6(10)+10=70
Hope this helps!

Answer:
a = 12 ft, b = 12 ft
Step-by-step explanation:
The triangle is 45 45 90 right triangle
so a = b
Ratio of leg : hypo. = a : a√2
Given hypo = 12√2, so legs a = b = 12
Answer
a = 12 ft, b = 12 ft
No;
it is exponentially always increasing
Answer:
The rate of return is 8%.
Step-by-step explanation:
The time span from 1794 to 2018 is (2018 - 1794) = 224 years.
Now, a penny i.e. 0.01 pounds of money as a principal gets the final sum of 345000 pounds after 224 years.
Here we have to calculate the rate of return if the interest is compounded yearly.
Using the formula of compound interest of r% APR, we get

⇒ 1 + 0.01r = 1.08
⇒ 0.01r = 0.08
⇒ r = 8% (Answer)
