Answer:

135°

Step-by-step explanation:

Since it's a right triangle, one angle will be 90° and the other given one is 45°. The total degrees in a triangle is 180 therefore ∠CAB is 45°.

Because ∠CAB is supplementary to ∠CAD, you have to subtract 180° -- since it's a straight line -- with 45°.

This gives you 135°

Products of equal value totaling $480 are sold to an audience of an unknown amount of people. the entrance fee is $10 per person

Sholpan [36]

Y = $\frac{10x+480}{x}$

This is because the total cost is 10x + 480 and then that needs to be divided by the amount of people.

Given ZW=20. Answer the questions please.

djyliett [7]

a) Corresponding angles of similar figures are congruent, so $\angle B \cong \boxed{\angle Z}$

b) Scale factor = (image)/(preimage). Since we are looking for ABCD to WZYX, this means that WZYX is the image and ABCD is the preimage. Thus, the scale factor is $\frac{25}{10}=\boxed{5/2}$

c) Since the scale factor is 5/2,

$\frac{20}{t}=\frac{5}[2}\\\\40=5t\\ \\ t=\boxed{8}$
