Sum of opp. interior angles = ext. angle
sum of all interior angle in a trangle = 180 deg
Answer:
.58c
Step-by-step explanation:
Find 42% of c
.42c
Then subtract that from c
c - .42c
.58c
.58c is 42% less than c

Answers:
tan(A) = 8/15
sin(A) = 8/17
cos(A) = 15/17
==================================================
Explanation:
The tangent ratio involves the opposite over adjacent. With respect to angle A, the opposite side is 8 units long as this side is as far as possible away from angle A. In contrast, the adjacent side is 15 units long because this leg is closest possible and the two are right next to one another.
Therefore,
tan(angle) = opposite/adjacent
tan(A) = BC/AC
tan(A) = 8/15
---------------
As for the other trig ratios, they are:
sin(angle) = opposite/hypotenuse
cos(angle) = adjacent/hypotenuse
which explains why sin(A) and cos(A) are 8/17 and 15/17 respectively.
