Please help:<br> In Δ ABC, sin A=88, sin B=42, and a =17, find the length of b.
iren2701 [21]

Answer:

Step-by-step explanation:

Use the law of sines.

\frac{sin A}{a} = \frac{sin B}{b} \\

Plug values in.

\frac{sin88}{17} = \frac{sin42}{b}\\

Cross multiply.

bsin88 = 17sin42\\b = 11.38

Hope that helps.

The surface area of a cube is 400 millimeters what is the surface area of a similar cube that is larger by a scale factor of 3
yuradex [85]
Larger by 3 means that the legnths of the sides are larger by 3 times
so we have a cube that has area of 400
surface area=legnth times width times 6 since it is a cube and legnth=width
so
SA=w^2 times 6

6w^2=400
divide by 6
w^2=200/3
square root both sides
w=√(200/3)
so w is 3 times larger
(3w)^2 times 6 is new area

w=√(200/3)
(3√(200/3))^2 times 6=9(200/3) times 6=600 times 6=3600

answer is 3600 ml^2

Square each term

50.41 + x² = 324

Subtract a from c

x² = 273.59

Find square root
