Answer:
b
Step-by-step explanation:
8-7-6-5-4-3-2-1-0-234 567 8 8
<span>In this triangle, the product of sin B and tan C is c/a or cos B, and the product of sin C and tan B is b/a cos C. We determine these as follows:
</span><span>sin B tan C = b/a (c/b) = c/a
</span><span>sin C tan B = c/a (b/c) = b/a
Hope this answers the question. Have a nice day.</span>
Because there can be multiple triangles with the same angles but completely different side lengths.
Answer:
132
Step-by-step explanation:
Alternate angles are equal. Therefore, A = B.
<u>Find x</u>
5x - 18 = 3x +42
2x = 60
x = 30
<u>Substitute x in angle A</u>
5(30) - 18 = 132
