Vita saved $72 last December. This amount represents 2/9 of the total amount she saved last year. What is the total amount Vita

GrogVix [38]

$\dfrac{2}{9} \text { of the saving} = \$72$

-----------------------------------------------
Find 1/9 :
-----------------------------------------------
$\dfrac{1}{9} \text { of the saving} = \$72 \div 2$

$\dfrac{1}{9} \text { of the saving} = \$36$

-----------------------------------------------
Find 9/9 :
-----------------------------------------------
$\dfrac{9}{9} \text { of the saving} = \$36 \times 9$

$\dfrac{9}{9} \text { of the saving} = \$324$

-----------------------------------------------
Answer: The total amount is $324.

Trigonometry... hellpp plzzz

rjkz [21]

Answer:

17.1 degrees

Step-by-step explanation:

This is a tangent question because angle XYZ is adjacent to 13 and opposite of 4. This means that we will have to use opposite/adjacent. This is very simple if you know the formula. Just plug those numbers in to get 4/13 = 0.3076923076923077. However, now we need to find it in degrees. If you have an inverse calculator near you, you would plug it in to get about 17.10, which rounds to 17.1.
