That mean the awner to question is 3 y is 3 just substract 6 minus 3
(2n+12) + (3n+18) = 180
⇒5n+30=180
⇒5n=150
⇒n=30
x=2n+12
=2(30)+12
=72°
The probilitu would be 1/3 becouse they are all evan and yeah
Answer:
tada
Step-by-step explanation:
y decreases
exponential decay, there for the function is exponential
y > 0
y=8
x=1,y=5
Answer:
AE = 7.5
Step-by-step explanation:
Since <BAC = , then;
<BAD = <DAE = <CAE = (complementary angles)
From ΔABC, applying the Pythagoras theorem to determine the length of side AC;
= +
= +
100 = + 25
= 100 - 25
= 75
AC =
Applying trigonometric function to ΔCAE,
Cos =
AE = × Cos
= 7.5
Therefore, AE = 7.5
