Answer: 18
Step-by-step explanation:
3(3)(2)
=(3)(6)
=18
A.) 75 x 60 = 4500 in an hour
4500 x 24 = 108000 in a day
108000 x 365 = 39420000 in a year
39420000 x 45 = <span>1,773,900,000 in 45 years
</span>B.)2200800 / 75 = 29344 mins
29344 / 60 = <span>489.066666667 hours
</span>489.066666667 / 24 = 20.37777778
you get it
It's an isosceles triangle so angles A and BCA are congruent.
Angle BCA is the supplement of BCD, so 180-109 = 71.
Angle A is congruent to that, so A=71 degrees.
Let's see if we can get that in the format they want, kind of as a proof.
1. ∠BCD=109° Reason: Given
2. AB ≅ BC Reason: Given
3. ∠BCA = 71° Reason: Linear pairs are supplementary
4. ΔABC is isosceles. Reason: Definition of isosceles
5. ∠A ≅ ∠BCA Reason: Isoceles triangle theorem
6. ∠A = 71° Reason: Def congruent
Answer: 71 degrees
2+2=4 because if you have 2 and you add another 2 you will have 4
