Answer:
130°
Step-by-step explanation:
∠BXF = ∠BXA + ∠AXF = 90° +40°= 130°
see ∠AXF =∠CXD opposite angles
∠CXD = 90° given
∠BXA = 40° given
Answer:
2n³ + 4
Step-by-step explanation:
Take off the parentheses (brackets) because there is nothing to multiply with it :
5 + 5n³ - 1 - 3n³
Now arrange the equation :
5n³ - 3n³ + 5 - 1
Subtract all the same variables :
5n³ - 3n³ = 2n³
5 - 1 = 4
Now arrange the equation again :
2n³ + 4
Answer: w=5 .
Step-by-step explanation: divide -9 on both sides which gives you 5 .So w=5 .
Since 1m = 100cm, then 67m = 6700cm + 7 cm = 6707cm.
