Answer:
see below
Step-by-step explanation:
Corresponding angles of similar triangles are equal and corresponding sides are proportional so:
m ∠P = m ∠D = 180° - (35° + 89°) = 56°
m ∠Q = m ∠F = 89°
m ∠ R = m ∠E = 35°
PR/DE =PQ/DF
40/DE = 20/24 cross multiply and solve for DE
DE = 40*24/20
DE = 48
scale factor is DF/PQ = 24/20 = 6/5 so FE = 6/5 *RQ =6/5 *36 = 43.2
Answer:
Step-by-step explanation:
The total height of the can is 20cm
Answer:
11.7 cm
Step-by-step explanation:
Using Pythagoras Theorem
AC² = AB² + BC²
AB = 4 cm
BC = 11 cm
AC² = 4² + 11²
AC = √4² + 11²
AC =✓137
AC = 11.704699911 cm
Approximately = 11.7 cm
Length AC = 11.7cm
Answer:
2x + 5y = -15 OR 2x + 5y + 15 = 0 Not sure they want it equal to zero
Step-by-step explanation:
y + 7 = -2/5(x - 10)
y + 7 = -2/5 x + 4
2/5x + y =-3
5(2/5 x + y = - 3)
2x + 5y = - 15
OR
2x + 5y + 15 = 0
