Answer:
m∠A= 52 degrees
Step-by-step explanation:
(Every triangle equals 180 degrees)
First you have to find angle C.
Step 1- Subtract
180-105= 75 *The line is a 180 degree angle
Now that you have the measure for two angles, you subtract.
53+75+x=180
128+x= 180
-128 -128
x=52
Answer:
$5.50
Step-by-step explanation:
k lets say x=movies while y=games
so, lets make a system of equations
2x+3y=14.50
3x+y=9.50
you can do substitution or elimination here it doesn't matter but you get x=2; y=3.5
movies cost 2 bucks, while games cost $3.50
so total is 3.50+2

On month -------- 10%
12 month ---------- x %
-------------------------------
x = 12*10/1 = 12*10 = 120%
Answer:
Step-by-step explanation:
let my present age=x
then 2(x-5)=x+2
2x-10=x+2
2x-x=2+10
x=12
my age=12 years
age of brother =12-3=9 years
age of sister= 9-2=7 years.
It would be A. Because 2 squared + 10 squared = 104
