)) How many solutions does this equation have?<br> 12 + 4t - 14t = -13t - 18

Orlov [11]

Answer:

t = -10

Step-by-step explanation:

Ok so,

12 - 10t = -13t -18

12 - 10t + 13t = -13t + 13t - 18

12 + 3t = -18

12 - 12 + 3t = -18 - 12

3t = -30

t = -10

hope this helps! have a good day!

Someone help pls :((

Answer:

56.714°

Step-by-step explanation:

Since we do not have a full angle of this proposed triangle, we must do this by splitting it into two right triangles instead of using the law of sines.

250m*sin(40°) = 250m*0.64278760968 = 160.696902422m

452.4m-160.696902422m=291.703097578m

Use pythagorean theorem:

$\sqrt{250^2 - 160.696902422^2}$

62500-25823.494448025787=36676.505552

$\sqrt{36676.505551974216}$ = 191.511110779m

arctan(291.703097578m/191.511110779m)≈56.714°
