Please help me <br> I have to solve the triangle with the law of sines
Nikitich [7]

Check the picture below.

and since a triangle has a sum of 180° for all interior angles.

A = 180 - 39.34 - 25

A = 115.66

\bf \cfrac{sin(25^o)}{44}=\cfrac{sin(A)}{a}\implies \cfrac{sin(25^o)}{44}=\cfrac{sin(115.66^o)}{a} \\\\\\ a\cdot sin(25^o)=44\cdot sin(115.66^o)\implies a=\cfrac{44\cdot sin(115.66^o)}{sin(25^o)} \\\\\\ a\approx 93.8452\implies \stackrel{\textit{rounded up}}{a = 93.85}

make sure your calculator is in Degree mode.

Given segment AC and point B that lies on AC, if AB = 9 and BC= 49, find AC
Ipatiy [6.2K]

Answer:

58

Step-by-step explanation:

Let's draw this out (see attachment).

We know that since B lies on AC, we have the points in order from left to right: A, B, C.

AB = 9, which is the left portion. BC = 49, which is the right portion. Then AC is simply the sum:

AC = AB + BC = 9 + 49 = 58

The answer is thus 58.

PLSSS HELPPPP I WILLL GIVE YOU BRAINLIEST!!!!!!
yulyashka [42]

Answer:

x=-10, y=-20

Step-by-step explanation:

Since both 2x and 3x+10 equals y, they equal each other.

2x = 3x + 10

x = -10

Substitute -10 for x

2(-10) = y

y=-20
