Answer:

7.8 = k

Step-by-step explanation:

Since the figures are similar, we can use proportions

----- = -------

b            j

Substituting the values in

6.5         k

----- = -------

4          4.8

Using cross products

6.5 * 4.8 = 4k

Help on this one please??
xenn [34]

Answer:

C = ~50 deg

Step-by-step explanation:

Apply the cosine theorem:

cos(C) = (CA^2 + CB^2 - AB^2)/(2*CA*CB)

           = (7.5^2 + 6.5^2 - 6^2)/(2*7.5*6.5)

           = 0.6410

=> C = ~50 deg

Hope this helps!
