Find the tangents of the acute angles in the right triangle. Write each answer as a fraction. WILL MAKE BRAINLIEST!!
patriot [66]

Answers:

  • tan(G) = 2
  • tan(H) = 1/2

=======================================

Explanation:

Recall that tangent is the ratio of opposite over adjacent

tan(angle) = opposite/adjacent

So for reference angle G, we say,

tan(G) = JH/GJ = 2/1 = 2

We'll treat tan(H) in a similar fashion, but the opposite and adjacent sides swap roles. That means we'll apply the reciprocal to the result above to get 1/2 for tan(H)

-----------

So we have this interesting property where

tan(G)*tan(H) = 2*(1/2) = 1

In general,

tan(A)*tan(B) = 1 if and only if A+B = 90 degrees

-----------

Side note: The side sqrt(5) isn't used at all.

Adam put $100 in a savings account. After 10 years, he had $1649 in the account. What rate of interest did he earn? Use the form
Korolek [52]
The formula is
A=p e^rt
A future value 1649
P present value 100
R interest rate?
T time 10 years
E constant
Solve the formula for r
R=[log (A/p)÷log (e)]÷t
R=(log(1,649÷100)÷log(e))÷10
R=0.28×100
R=28%

To use the elimination method, you can add the two equations in a system of equations to eliminate one of the variables.
oksano4ka [1.4K]

Answer:

x=1 y=19

Step-by-step explanation:

Let's solve your system by elimination.

−9x+y=10; 10x−y=−9

−9x+y=10

10x−y=−9

Add these equations to eliminate y:

x=1

Then solve x=1 for x:

x=1

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

−9x+y=10

Substitute1forxin−9x+y=10:

(−9)(1)+y=10

y−9=10(Simplify both sides of the equation)

y−9+9=10+9(Add 9 to both sides)

y=19

Hope this helps, I don't really get the answer choices though....
