Mashutka [201]

Answer:

$y = \frac{7}{3}x +3$

Step-by-step explanation:

Slope-intercept formula: $\frac{y_2-y_2}{x_2-x_1}$

$\frac{y_2-y_2}{x_2-x_1}\\\\\frac{3-10}{0-3}\\\\\frac{-7}{-3}\\\\\frac{7}{3}$

$y = mx + b$

$y = \frac{7}{3}x +b$

$3 = \frac{7}{3}(0)+b$

$3 =0+b$

$3 =b$

$y = \frac{7}{3}x +3$

Hope this helps!

SOMONE PLEASEE HELPPP MEEEEEEEE!!!

katen-ka-za [31]

Answer:

? = 36 degrees

Step-by-step explanation:

To find this measure, we use the appropriate trigonometric ratio

from the question, the angle faces the length 26 which represents the opposite

the length 44 faces the angle 90, which is the hypotenuse

The trigonometric ratio that connects both is the sine

The sine of an angle is the ratio of the opposite to the hypotenuse

Thus;

sine ? = 26/44

? = arc sine (26/44)

? = 36
