Given triangle abc ~ triangle xyz, what is the value of cos(z)

cos(Z) = 12/13

Step-by-step explanation:

Given that the triangles ABC and XYZ are similar (their corresponding angles are congruent and the corresponding sides are in proportion), then cos(Z) is equal to cos(C).

From the picture attached:

cos(C) = adjacent/hypotenuse

cos(C) = 12/13

Multiplication property of zero

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
