Step-by-step explanation:
You have to make x as a subject by substracting 4 on both sides :
15 < 4 + x
15 - 4 < 4 + x - 4
11 < x
x > 11
Answer: Similar figures are always the same shape, but not the same size. They have equal angles but not equal side lengths. Check out a big square and a small square. They're both squares because they have four sides and four equal angles, but the sides aren't the same length.

Answer:
C. sin(90° - θ)
Step-by-step explanation:
A trig function of an angle equals the cofunction of the angle's complement.
The cofunction of cosine is sine, and the complement of θ is 90° - θ.
∴ cosθ = sin(90° - θ)
Answer:
13
Step-by-step explanation:
The mean of a set of quantities is their sum divided by the number of them.
<h3>Mean</h3>
((p+1) +(q+2) +(r+3) +(s+4) +(t+5))/5
= (p +q +r +s +t)/5 +(1 +2 +3 +4 +5)/5
= mean(p, q, r, s, t) +15/5
= 10 +3 = 13
The mean of p+1,q+2, r+3,s+4 and t+5 is 13.
