Answer: 25,5 p</h3>
Step-by-step explanation:
- 16 , 8 % = ? p
- 100% = 152 p
I'm only going to alter the left hand side. The right side will stay the same the entire time
I'll use the identity tan(x) = sin(x)/cos(x) and cot(x) = cos(x)/sin(x)
I'll also use sin(x+y) = sin(x)cos(y)+cos(x)sin(y) and cos(x+y) = cos(x)cos(y)-sin(x)sin(y)
So with that in mind, this is how the steps would look:
tan(x+pi/2) = -cot x
sin(x+pi/2)/cos(x+pi/2) = -cot x
(sin(x)cos(pi/2)+cos(x)sin(pi/2))/(cos(x)cos(pi/2)-sin(x)sin(pi/2)) = -cot x
(sin(x)*0+cos(x)*1)/(cos(x)*0-sin(x)*1) = -cot x
(0+cos(x))/(-sin(x)-0) = -cot x
(cos(x))/(-sin(x)) = -cot x
-cot x = -cot x
Identity is confirmed
Answer:
-6 - square root 31, -6 + square root 31

Answer:
X=66°
Step-by-step explanation:
Because it is an isosceles triangle, the 2 missing angles are going to be the same size.
Subtract 48 from the total degree of the triangle which is 180.
180-48= 132
now you di ed that by 2 and you’ll know the missing angle.
132/2= 66
