180-40=140
140/2=70
angle RST=70
Answer:
If your trying to find m then
-10 = 2m + 4
-4 -4
-14 = 2m
then you divide
-14/2 and 2/2 < this one cancels out
-7 = m
Answer:
6 cm and 8 cm
Step-by-step explanation:
Use Pythagorean theorem:
c² = a² + b²
10² = x² + (x+2)²
100 = x² + x² + 4x + 4
0 = 2x² + 4x − 96
0 = x² + 2x − 48
0 = (x − 6) (x + 8)
x = 6 or -8
x must be positive, so x = 6. Which means x+2 = 8.
I'm not very good with word problems but if I am correct it is 660 minutes so about 11 hours?
Answer:
a line parallel has the same slope and different y-intercept, and the slope of the perpendicular line would be -3/5
Step-by-step explanation:
3x + 5y = 4
5y = -3x + 4
y = -3/5x + 4/5
