Answer:
<A= 65 & <B=78
Step-by-step explanation:
this is because first we must find X, so in order to do so we must add together all angle measures, then make that equal 180. So
(2x-9)+(2x+4)+x=180
2x+2x+x-9+4=180
5x-5=180
5x=180+5
5x=185
X=185/5
x=37
Then we just have to plug in the value of x into the angle measurements.
Answer:
4
Step-by-step explanation:
n/6 + 2 If n = 12
12/6 + 2
2 + 2 = 4
Equation:
6(1/x) = 2(1/7)
-----
6/x = 2/7
-----
2x = 42
x = 21
Answer:
a=1/3
Step-by-step explanation:
from the point on the graph
x=4 and y=8
substitute them into the equation:
y=a(x-2) (2x+4)
you will get
8=a(4-2) (2(4)+4)
8=a(2) (8+4)
8=a(2) (12)
8=2a×12
8=24a
divide both sides by 24
8/24=24a/24
1/3=a or a=1/3
