Help with MATH please

evablogger [386]

Answer:

Step-by-step explanation:

4). By applying cosine rule for angle R,

cos(∠R) = $\frac{\text{Adjacent side}}{\text{Hypotenuse}}$

cos(33°) = $\frac{x}{19}$ [Equation]

x = 19cos(33°)

= 8.39

5). By applying sine rule,

cos(20°) = $\frac{\text{Opposite side}}{\text{Hypotenuse}}$

cos(20°) = $\frac{15}{x}$ [Equation]

x = $\frac{15}{\text{cos}20}$

x = 15.96

6). By applying tangent rule,

tan(40°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(40°) = $\frac{15}{x}$ [Equation]

x = $\frac{15}{\text{tan}40}$

x = 17.88

Please help me. Is (3,13) a solution of the equation y=4x?

SpyIntel [72]

Well I don't know. Let's find out.

When you say (3,13), that means 'x' is 3 and 'y' is 13.
We'll plug those into the equation, and see if the equation is a true statement.

y = 4x

13 = 4 (3)

4 (3) means 4 x 3, and that's 12.

So the equation says 13 = 12 .

Is that a true statement ?
I don't think so.

So (3, 13) is NOT a solution of y = 4x
