Okay so every triangle will have 3 angles that add to 180 degrees. You are given that A=65 which means that B + C will have to add to 115. You are given that B= (3x-10) and C=2x, plug this into B+C=115. So
3x-10+2x=115, isolate x, 5x=125, divide both sides by 5 and you get that x=25. This makes B=65, and C=50. Just to check, if you add these together you get 180 degrees.
B, im hundred percent sure its right
Answer:
55,98,27
Step-by-step explanation:
To solve for the angles we must first find y with this equation
3y+5+2y-7=153
We can simplify this
5y-2=153
153+2=155
155/5=31
y=31
We now know y and can plug it into the angles
<A=2y-7
2(31)-7
62-7
55
<A=55
<B=3y+5
3(31)+5
93+5
98
<B=98
Now time for the last angle
Since angle BCA and DCB are next to each other they add up to 180
153+x=180
180-153=27
x=27
<BCA=27
Answer:
$15.6
Step-by-step explanation:
Based on the given information, it is $15.6. However, it never specified how many hours she works a day and how many days of the week she works, so we must assume it is just 624/40.
