Answer:
Step-by-step explanation:
<u>ΔABD ≅ ΔAEC because:</u>
- AD = AC = 17
- ∠A is common and congruent to itself
We have two sides and the included angle congruent - SAS
<u>Corresponding parts of congruent figures are congruent:</u>
Now, <u>∠CED is exterior angle and exterior angle is same as sum of non-adjacent interior angles:</u>
- m∠CED = m∠A + m∠C
- 79° = 42° + p°
- p = 79° - 42°
- p = 37°
Answer:
7.5mph
Step-by-step explanation:
Speed = Distance / Time
Speed = 15 ÷ 2
Speed = 7.5 mph
Step-by-step explanation:
100 = 12
300 + 50 = 36 + 6 = 42 L
Use the distance formula
d = sqrt ((y2-y1)^2 + (x2-x1)^2))
= sqrt ( (5 sqrt2 - sqrt2)^2 + ( -3sqrt5 - sqrt5)^2)
= sqrt [( 4sqrt2)^2 + (4sqrt5)^2]
= sqrt (32 + 16*5) = sqrt 112 = sqrt16 * sqrt7 = 4 sqrt7
The answer is 4 sqrt7
