Not sure what x' means but
seems to be the reverse distributive property
normally written as
a(b+c)=ab+ac
we can see the similarity
a(x'+y)=ax+ay
distributive property
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:
Sum of all angles of a triangle = 180
x + 64 + x + 45 + 79 = 180
Combine like terms.
2x + 188 = 180
2x = 180 - 188
2x = - 8
x = -8/2
x = -4
x + 64 = -4 + 64 = 60
x + 45 = -4 + 45 = 41
