Answer:

The answer to your question is:

Step-by-step explanation:

Data

B = 70°

c = 14

Process

                sin Ф = b / c

                b = c sinФ

                b = 14 sin 70

                b = 14 x 0.94

                b = 13.16

               cos Ф = a/c

               a = c x cos Ф

               a = 14 cos 70

               a = 14 x 0.34

               a = 4.76

 C = 90° it is a right angle

A = 180 - 90 - 70

A = 180 - 160

A = 20°

What is the value of y in the solution to the system of equations? 1/3x + 1/4y = 1 2x-3y=-30​
Zepler [3.9K]

Answer:

<h2>y = 8</h2>

Step-by-step explanation:

\left\{\begin{array}{ccc}\dfrac{1}{3}x+\dfrac{1}{4}y=1&\text{multiply both sides by 12}\\2x-3y=-30\end{array}\right\\\left\{\begin{array}{ccc}12\!\!\!\!\!\diagup^4\cdot\dfrac{1}{3\!\!\!\!\diagup_1}x+12\!\!\!\!\!\diagup^3\cdot\dfrac{1}{4\!\!\!\!\diagup_1}y=12\cdot1\\2x-3y=-30\end{array}\right\\\left\{\begin{array}{ccc}4x+3y=12\\2x-3y=-30&\text{multiply both sides by (-2)}\end{array}\right\\\underline{+\left\{\begin{array}{ccc}4x+3y=12\\-4x+6y=60\end{array}\right}\qquad\text{add both sides of the equations}

.\qquad9y=72\qquad\text{divide both sides by 9}\\.\qquad y=8
