Find the indicated side of the right triangle. 45 y 9 45° х y = [?]

Mathematics

Answer:

y = 9√2

Step-by-step explanation:

By applying Pythagoras theorem in the given right triangle,

(Hypotenuse)² = (leg 1)² + (leg 2)²

y² = 9² + x²

By the property of isosceles triangle,

Two angles of the right triangle are equal in measure, opposite sides of these equal angles will be equal in measure.

Therefore, x = 9

y² = 9² + 9²

y² = 81 + 81

y² = 162

y = √162

y = 9√2

For two days, your boss decides to double the amount you make if on day 1, you make $70 dollars and on day 2, you make$80 dollar
Hoochie [10]

Answer:

300

Step-by-step explanation:

Day 1: $70

Day 2: $80

Total commission = day 1 × 2 + day 2 × 2

= 70 × 2 + 80×2

= 140 + 160

= 300

Or

Total commission = 2(day 1 + days 2)

= 2(70 + 80)

= 2(150)

x = 300

(multiple choice) plz help me!!
Kazeer [188]

Answer:

x is the missing side (x > 0)

because this is a right triangle, using Pythago theorem, we have:

x² + 4² = 12²

⇔ x² = 12² - 4²

⇔ x² = 128

=> x ≈ 11.3

How many solutions does the following system of equations have?
True [87]
We will use a method of substitution.
y = 5/2 x + 2 
2 y = 5 x + 4   ⇒  2 ( 5/2 x + 2 )= 5 x + 4
5 x + 4 = 5 x + 4
0 x = 0            ⇒  x, y ∈ R
Answer: D)   
This system has infinitely many solutions.

Which expression represents the approximate length
Viktor [21]

The expression that represents the approximate length of BC is; A: (3) sin(66)/sin (38)

<h3>Trigonometric Ratios</h3>

From the given triangle ABC, we see that;

∠A = 66°

∠C = 38°

AB = 3

Thus using sine rule, we have;

AB/sin C = BC/sin A

3/sin 38 = BC/sin 66

BC = (3sin 66)/sin 38

BC = 4.45
