Answer:
∠ 1 = ∠ 2 = 75°
Step-by-step explanation:
The sum of the 3 angles in Δ CDE = 180°
sum the angles and equate to 180°
∠ 1 + 38° + 67° = 180°
∠ 1 + 105° = 180° ( subtract 105° from both sides )
∠ 1 = 75°
∠ 1 and ∠ 2 are vertically opposite angles and are congruent , so
∠ 2 = 75°
Answer:
Step-by-step explanation:
X²/X³
Using the law of indices, when an expression has same base, take a base and subtract the powers in terms of division
X²÷X³ = X^(2-3) = X^-1
