Answer:
AC ≈ 5.03
Step-by-step explanation:
We can solve the problem above using the trigonometric ratio, they are;
SOH CAH TOA
sin Ф = opposite / hypotenuse
cosФ= adjacent/ hypotenuse
tan Ф = opposite / adjacent
From the diagram above, in reference to angle B;
opposite =AC and adjacent =BC
Since we have opposite and adjacent, the best formula to use is
tanФ = opposite / adjacent
tan B = AC / BC
tan 40 = AC/ 6
Multiply both-side of the equation by 6
6× tan 40 = AC/ 6 × 6
At the right-hand side of the equation, 6 will cancel-out 6 leaving us with just AC
6×tan 40 = AC
5.034598 = AC
AC ≈ 5.03 to the nearest hundredths
Answer:x= -3 {x=1 tx= -2 {x =1
Step-by-step explanation:
Answer=A
Let's write the an equation in slope intercept for for the line.
y-intercept=10
slope=rise/run=15/2=7.5
equation:
y=mx+b
y=7.5x+10
Solve for x=7
y=7.5(7)+10
y=52.5+10
y=62.5
Answer=A
