Choose letters to  represent the unknowns:  x and y.  We are told that x-y = 361.

We could choose any number for x and then calculate y:

Suppose we let x = 500.  Then 500 - y = 361, and y = 139.

Suppose we let x = 1.  Then 1 - y = 361, and y = -360.

And so on.

Solve for x in the triangle, Round your answer to the nearest tenth.
juin [17]

Answer:

14.6 = x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp/ hyp

sin 66 = x/16

16 sin 66 = x

14.61672732 =x

To the nearest tenth

14.6 = x

Two angles are complementary. The measurement of ∠GHI is (5x+6)∘ and ∠JKL measures (3x+4)∘. What are the measures of the two ang
Alex777 [14]

Answer:

Angle GHI measures 56º, and angle JKL measures 34º.

Step-by-step explanation:

Complementary Angles:

If two angles are complementary, the sum of their measures is 90º.

∠GHI is (5x+6)∘ and ∠JKL measures (3x+4)∘.

Since they are complementary:

5x + 6 + 3x + 4 = 90

8x + 10 = 90

8x = 90 - 10

8x = 80

x = \frac{80}{8}

x = 10

Measures:

GHI: 5*10 + 6 = 50 + 6 = 56º

JKL: 3*10 + 4 = 30 + 4 = 34º.

Angle GHI measures 56º, and angle JKL measures 34º.

Evaluate 90 divided by X to the second power + y
Arlecino [84]

Answer:  =34

=3⋅3⋅3⋅3

=81

For example, 3 to the power of -4:

=3−4

=134

=13⋅3⋅3⋅3

=181

=0.012346

Step-by-step explanation: the solution is expanded when the base x and exponent n are small enough to fit on the screen. Generally, this feature is available when base x is a positive or negative single digit integer raised to the power of a positive or negative single digit integer. Also, when base x is a positive or negative two digit integer raised to the power of a positive or

negative single digit integer less than 7 and greater than -7.

hopefully this is right :/
