Step-by-step explanation: SA = 2 × l × w + 2 × l × h + 2 × w × h
Answer:
Step-by-step explanation:
Sum of angles in a Δ= 180°
x + 2x +3x = 180
6x= 180
Divide both sides by 6
x=30
sooo x= 1×30= 30, 2x= 2×30= 60, 3x=3×30= 90
since 30+60+90= 180
∴the angles are 30°,60° and 90° respectively
Answer:
x ≈ 26.4
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos47° =
=
=
( multiply both sides by x )
x × cos47° = 18 ( divide both sides by cos47° )
x =
≈ 26.4 ( to the nearest tenth )
