Answer:
a) Similar triangles are triangles with the same shape but not necessarily the same size
b) 15/45 = 8/x
1/3 = 8/x (simplify the 15/45)
x = 8 * 3 (cross multiplication)
x = 24
c) y^2 = 15^2 + 8^2 (Pythagoras theorem)
y = *square root of* 15^2 + 8^2
y = 17
1/3 = 17/z
z = 17 * 3 (cross multiplication)
z = 51
Answer:
x≤-20
Step-by-step explanation:
x+ 17≤-3
Subtract 17 from each side
x+ 17 -17≤-3-17
x≤-20
Answer:
1g
Step-by-step explanation:
Geometric mean =x=<span>√(5 × 20)
=</span>√100
=10
X= -1 beacuse negative one plus one is 0 and that will equal zero for both sides
