Question

in angle ABC measure angle B= 90° AC=17 BC=8 find AB and also find sinC, cosC, tanA​

Answer 1

Answer:

AB =  15

sin C = 15/17

cos C = 8/17

tan A = 8/15

Step-by-step explanation:

(AC)² = (BC)² + (AB)²

(17)² = (8)² + (AB)²

(AB)² = 289 - 64

(AB)² = 225

AB = √225

AB = 15

NOW,

• sin C =  AB/ AC = 15/17

• cos C = BC/AC = 8/17

• tan A = BC/AB =  8/15
