Answer:
Angle D is equal to 80.
Step-by-step explanation:
We know that the sides are congruent and that angle ACB is congruent to angle ECD by the vertical angles theorem.
Triangles' angles always add up to 180.
180 - 70 - 30 = 80
angle D is equal to 80.
Answer:
D.) 4 1/20
Step-by-step explanation:
2 1/4 * 9/5
Change 2 1/4 to an improper fraction
4*2+1 = 9/4
9/4 * 9/5
Multiply straight across the numerators and then straight across the denominators
9 * 9 = 81 4 * 5 = 20
81/20
Change this back into a mixed number
81 divided by 20 = 4 1/20
