Answer:
11/4
Step-by-step explanation:
.
tan(90-x)=cot(x) by cofunction identity
tan(90-x) is therefore the reciprocal value of tan(x) since tan(x) is the reciprocal of cot(x) or vice versa.
tan(90-x)=11/4 since tan(x)=4/11
16
Explanation:
a = 2
c = 8
ac
2 · 8 = 16
From the Pythagorean theorem we have:
<em>subtract b² from both sides</em>
