Answer:
a.70. b.50
Step-by-step explanation:
- If Cartie takes $10 from her account for 7 days she would have taken $70 out.
- Next we look at the net problem it is asking us how much is left we already know from the equation above that we need to subtract 70 from 120
- We now have both answers A. being that she would have taken $70 in total out of her account and B. being that she would have $50 left in her account.
I think it’s the triangle
Answer:
m∠B = 
.
Step-by-step explanation:
Since the three sides of the triangle are given, then we apply cosine rule.
= 
+ 
- 2ac Cos B
But, a = 660 cm, b = 680 cm, and c = 100 cm.
So that;
= 
+ 
-2(660 x 100) Cos B
462400 = 435600 + 10000 - 132000 Cos B
462400 = 445600 - 132000 Cos B
132000 Cos B = 445600 - 462400
= -16800
Cos B = 
= -0.1273
B = 
-0.1273
=
Thus, measure of ∠B is .
It is 17ft because i know im in high school and the diagram show
B. 12.02 < 12.20.........................................
