Answer:
<h3>
m∠UVT = 97°</h3>
Step-by-step explanation:
Given m∠WVU = 169°, m∠WVT = (2x + 20)° and m∠UVT = (3x + 19)°, according to the diagram shown, it is seen that;
m∠WVU = m∠WVT +m∠UVT
Substitute the given parameters into the function as shown;
(2x + 20)°+(3x + 19)° = 169
collect like terms
2x+3x+20+19 = 169
5x+39 = 169
5x = 169-39
5x = 130
x = 130/5
x = 26°
Since m∠UVT = 3x+19, substitute x = 26 into the function
m∠UVT = 3(26)+ 19
m∠UVT = 78+19
m∠UVT = 97°
She started with x books. She purchased 3 more.
Add the two amounts (x and 3) to find out the number of books she has now.
Now she has x + 3 books.
We are told she now has 11 books, so x + 3 must equal 11.
The equation is x + 3 = 11
Answer: C.) x + 3 = 11
(x - 4y)²
(x - 4y)(x - 4y)
x(x - 4y) - 4y(x - 4y)
x(x) - x(4y) - 4y(x) + 4y(4y)
x² - 4xy - 4xy + 16y²
x² - 8xy + 16y²
Answer is 16 hours.
4/5=16/20
So 16 x 1 =16 hours.
Hope this helps.
I think you just use the formula v= lXwXh. Volume equals length times width times height
