Answer:

x = 9.2

x =22.0

x = 8.7

Step-by-step explanation:

Required

Find x

(a)

x is calculated using tangent formula

\tan(57) = \frac{x}{6}

Make x the subject

x = 6 * \tan(57)

x = 6 * 1.5399

x = 9.2394

x = 9.2 --- approximated

(b):

x is calculated using cosine formula

\cos(60) = \frac{11}{x}

Make x the subject

x = \frac{11}{\cos(60)}

x = \frac{11}{0.5}

x =22.0

(c):

x is calculated using sine formula

\sin(60) = \frac{x}{10}

Make x the subject

x = 10 * \sin(60)

x = 10 * 0.8660

x = 8.660

x = 8.7 --- approximated

Brut [27]
80 = 5 x 4 x 4

they have 4 flavors of icecream

you get this by multiplying all the variables and how many different possibilities each variable can be

so,
5 different syrups (5)
4 different candy toppings (4)

from that you know 5 x 4 x ? = 80

so 5 x 4 = 20, and 20 x 4 = 80

so 4 different flavors of ice cream (4)
