Answer:
x 4 y 1
Step-by-step explanation:
5x4-2 is 18 3x4+3 is 15
Pythagoras; a^2 + b^2 = c^2 So, (6.7)^2 + (5.5)^2 = 75.14 then square root to get, 8.668 (to 3 d.p) hope this helps!!
Answer:
10 units
Step-by-step explanation:
Given that:
Cos a = 3 /5
From trigonometry ;
Cos θ = Adjacent / hypotenus
Side Adjacent angle a = 3 = FD
Hypotenus = 5 = DE
3 / 5 = FD / DE
FD = 6 units
3/5 = 6/DE
DE * 3/5 = 6
DE = 6 ÷ 3/5
DE = 6 * 5 /3
DE = 30 /3
DE = 10 units
Answer:
