Answer:
143÷g=g
Kinda easy.
I hope this is what you meant.
And I hope this helps you! ;P
To solve this problem you might have to use this formula y=a(1+r)^t A=amount of money you already have 1= a set number R= rate T= time YOUR GIVENS ARE: A=4000 R= 3.5% (0.035) decimals T= 3 years NOW lets plug IN everything in the FORMULA y=4000(1+.035)^3= $4434.87. NOW lets subtract 4000-4434=434. She earned $434 of simple interest.
In this problem you only need to find the x value of one triangle. If you notice, this is a rectangle that has been cut in half by a diagonal into two equal right triangles. So both the top and bottom part are equal to 500 and both have an angle equal to 10 degrees.
Now looking at the problem, you would have to use tangent since 500 is adjacent and your X value is opposite.
Tan(10) = (X/500)
Now solve by multiplying each side by 500
X= Tan(10) 500 put this in a calculator
Answer is 88.2 degrees
