Solve for a side triangles please help it’s urgent please answer

rodikova [14]

Answer:

AC ≈ 2.87

Step-by-step explanation:

Using the sine ratio in the right triangle

sin35° = $\frac{opposite}{hypotenuse}$ = $\frac{AC}{AB}$ = $\frac{AC}{5}$

Multiply both sides by 5

5 × sin35° = AC , thus

AC ≈ 2.87 ( to the nearest hundredth )

Through point (0, 10) and PERPENDICULAR to the line through (-2, -9) and (-4, -17)?

inn [45]

Compute the slope of the line through (-2, -9) and (-4, -17):

$\dfrac{-9-(-17)}{-2-(-4)}=\dfrac82=4$

Any line perpendicular to this line will have slope -1/4. The one that passes through (0, 10) satisifes

$y-10=-\dfrac14(x-0)\implies\boxed{y=10-\dfrac x4}$
