Answer:
c
Step-by-step explanation:
Answer:
m<A = 120°
m<C = 45°
Step-by-step explanation:
We can use the triangle sum theorem to find the measures of the angles.
m<A + m<B + m<C = 180°
Then substitute in their given values.
12x + 12 + 15 + 3x + 18 = 180°
Now simplify the equation and you get
15x + 45 = 180°
Continue to solve
15x = 135
x = 9°
Now substitute this value of 9 for the angle expressions of <A and <C
(12 x 9) +12 = m<A
m<A = 120°
(3 x 9)+ 18 = m<C
m<C = 45°
Hope this helps. To check your answer you can add up all the answers to see if it equals 180°.
Answer: 10.11 gallons
Step-by-step explanation: So I took the 8 gallons + 8liters. I figured you can’t do that. So i took the 8 Liters and converted it into gallons. And i got 2.11 gallons. So i did the math and added 2.11 + 8 gallons. The result was 10.11 gallons. Hope that will work
Those | | means that whatever the number inside is, will always be positive so it is equal
Answer:
I’ve got the graphs for both equations below.
With y = 7/2x + 3
y = -x-6
I used substitution with simultaneous equations and got x = -2 and y = -4 :)
