Answer:
<em>22.62°</em>
Step-by-step explanation:
Considering △ABC. If angle B C A is a right angle, then;
m<BCA = 90 degrees
Given also
AB = 13
BC = 12
AC = 5.
According to SOH, CAH TOA;
Sin <B = AC/AB
Cos <B = BC/AB
Substitute the given values
Sin B = 5/13
B = arcsin(5/13)
B = 22.62
Cos B = 12/13
B = arccos (12/13)
B =22.62
<em>Hence the angles that make sinB = cosB is 22.62°</em>
2t<-4 divide both sides by 2
t<-2
...
7t>49 divide both sides by 7
t>7
So t=(-oo,-2) and t=(7,+oo)
t=(-oo,-2)U(7,+oo)
Answer:
<span>r≤−10∪r≥4</span>
Explanation:
<span><span>|<span>r+3</span>|</span>≥7</span>
SOLUTION 1
<span>r+3≥7</span>
<span>r≥4</span>
SOLUTION 2
<span>r+3≤−7</span>
<span>r≤−10</span>
Since the two inequalities do not intersect when graphed, the solution set is
<span>r≤−10∪r≥<span>4 </span></span>
