In Triangle ABC, AC is extended through C to D. If

DENIUS [597]

Answer:

X = 5 unit

Step-by-step explanation:

Given as , ABC is a Triangle ,

AC extended to through C to D

∠BAC = 6x + 10

∠ABC = 6x - 10

∠BCD = ∠ 8x + 20

When c extended to D then , ∠BCD is an external angle

∵ External angle = Sum of opposite internal angles

Or ,∠BCD = ∠BAC + ∠ABC

Or, ∠ 8x + 20 = 6x + 10 + 6x - 10

Or, ∠ 8x + 20 = 12x

Or, 12x - 8x = 20

∴ 4x = 20

So, x = $\frac{20}{4}$ = 5

Hence the value of X = 5 unit Answer

Answer:

36.81233927

13.02532494

Step-by-step explanation:

You need to use the law of sine for both of them

the law of sine is as follows:

$\frac{a}{\sin(A)}=\frac{b}{\sin(B)}=\frac{c}{\sin(C)}$

Question 1:

$\frac{15}{\sin(64)}=\frac{10}{\sin(y)}\\y=36.81233927$

Question 2:

Let x= AB

Start by solving for the missing angle, 53

$\frac{8.4}{\sin(31)}=\frac{x}{\sin(53)}$

x= 13.02532494

??????????????????????????????

You want to find the time t such that

$\$1000 = \$200 e^{0.04t}$

Divide both sides by $200 :

$\dfrac{\$1000}{\$200} = 5 = e^{0.04t}$

Take the logarithm of both sides:

$\ln(5) = \ln(e^{0.04t}) = 0.04t\ln(e) = 0.04t$

Divide both sides by 0.04 and solve for t :

$t = \dfrac{\ln(5)}{0.04} \approx 40.24 \approx \boxed{40}$

How do you factor 8x+56?

Aleksandr [31]

If you mean how do you get x by it's you divide both sides by 8, to cancel out the multiplication between x and 8, meaning that it would end up being x=7, sorry if that didn't answer your question correctly.
