Answer:

C

Step-by-step explanation:

Using the Sine rule in Δ ABC

Calculate the measure of ∠ C

∠ C = 180° - (64 + 85)° = 180° - 149° = 31° , then

$\frac{sin31}{9.3}$ = $\frac{sin85}{b}$ → C

Answer:

7√2

Step-by-step explanation:

Thank to the give angle we can say that the two legs are congruent

b = $\sqrt{7^2 + 7^2} = \sqrt{49+49} = \sqrt{98}$

98/2 = 49

49/7 = 7

7/7 = 1

98 = 7^2 x 2

√98 = 7√2

Answer:

$y=-10x+43$

Step-by-step explanation:

We need to put this line into slope-intercept form, which is $y=mx+b$ , where $m$ is the slope and $b$ is the $y$ -intercept.

The slope is rise over run, how much the $y$ value changes for one $x$ value. This can be found with the equation: $m=\frac{y_2-y_1}{x_2-x_1}$ where $(x_1,y_1)$ and $(x_2,y_2)$ are points on the line. Plugging in the first two points:

$m=\frac{3-13}{4-3}=-10/1=-10$

We know them that $m=-10$ . This gives us for now $y=-10x+b$ .

Now, to solve for $b$ , plug in any one of the points (I'll use (3,13)):

$13=-10(3)+b$

$13=-30+b$

$b=43$

This gives us the equation $y=-10x+43$ .
