Use the image below to answer the following question. Find the value of sin x® and cos yº What relationship do the ratios of sin
Flauer [41]

Answer:

sin(x) and cos(y) are equal and have ratio of 1 : 1

First find the missing hypotenuse using Pythagoras theorem:

a² + b² = c²

12² + 5² = c²

c = √144+25

c = 13

using sine rule:

sin(x) = \dfrac{opposite}{hypotenuse}

sin(x) = \dfrac{5}{13}

using cosine rule:

cos(y) = \dfrac{adjacent}{hypotenuse}

cos(y) = \dfrac{5}{13}

Help me please thank you
katen-ka-za [31]

Answer:

Step-by-step explanation:

A+N+J=310

A=N*2 =>N=A/2

N=J*3 =>J=N/3

N=?

N*2+N+N/3=310

3N+N/3=310

(9N+N)/3=930/3

10N=930

N=930/10

N=93

What is the justification for step 2 in the solution process?12 - x = 7x +32Step 1: -X = 7x + 20Step 2: -8x = 20
HACTEHA [7]
Answer:

The subtraction property of equality

Option A is correct

Explanation:

The given equation is:

12 - x = 7x + 32

Subtract 12 from both sides

12 - 12 - x = 7x + 32 - 12

-x = 7x + 20 (Step 1)

From step 1 above, subtract 7x from both sides

-x - 7x = 7x - 7x + 20

-8x = 20 (Step 2)

Since we subtracted 7x from both sides to get step 2, the justification for step 2 is the subtraction property of equality
