Using a/sinA=c/sinC
a=24 c=38
A=39
24/sin39=38/sinC
SinC=38sin39/24

Answer:

85.20

Step-by-step explanation:

We have to find the measure of ∠c.

By applying sine rule in the triangle.

\frac{SinA}{BC}=\frac{Sinc}{AB}

Sin A × AB = Sin c × BC ( By multiplication )

( Sin 39° ) × 38 = 24 sinc

sin c = \frac{38*0.62932}{24} = 0.99642

c = sin^{-1} = ( 0.99642 )

= 85.15 ≈ 85.20

barxatty [35]

Answer:

y = (x+2)²-2

Step-by-step explanation:

Use the vertex form y = a(x-h)²+k. Plug in the vertex for h and k. Solve for a and you will get 1 for that value. You can check your answers by plugging in both of those points to make sure.

Which is the best estimate for the sum of 3/8 and 1/12¿
SashulF [63]
Estimating is an educated guess, so 3/8 is just less than half, and 1/12 is just a bit more than 0.  So you could estimate that 3/8 + 1/12 = roughly 1/2

<span> if you add 3/8 and 1/12 you get 11/24</span>
