Answer:

b. 46°

Step-by-step explanation:

In a circle, measure of minor arc is equal to the measure of its corresponding central angle.

$\therefore m\overset{\frown} {BD} = m\angle BAD = 148°\\ \because m\overset{\frown} {BD}= m\overset{\frown} {BC}+ m\overset{\frown} {CD}\\ \therefore 148° = 102° + m\overset{\frown} {CD}\\ \therefore m\overset{\frown} {CD}= 148° - 102°\\\huge\purple {\boxed {\therefore m\overset{\frown} {CD}= 46°}} \\$

nadezda [96]

Answer:

4277.6

Step-by-step explanation:

Hello, I can help you with this

Step one

find the profit using a simple rule of three

4000 ⇔ 100%

then, how much(x) is 6.94?

x ⇔ 6.94%

the relation is

$\frac{4000}{100}=\frac{x}{6.94}\\ solve\ for\ x\\\\x=\frac{4000*6.94}{100}\\x=277.6\\$

the profit is 277.6

hence, her balance after one year is the initial amount plus interest earned

balance= 4000+277.6

balance= 4277.6
