Mathematics
1 answer:
Debora [2.8K]2 years ago
4 0

Answer:

C. 82.43

Step-by-step explanation:

acb's angle is 315 degrees because

360 - 45 = 315

arc length is in radians

arc length is radius times (angle times (pi÷180))

arc length is 15 times (315 times (pi÷180))

arc length is 82.43

In triangle ABC mzA -45, mzB = 40", and a = 7. Which equation should you<br> solve to find b?
yaroslaw [1]

Answer:

Option A. \frac{sin(45\°)}{7}=\frac{sin(40\°)}{b}

Step-by-step explanation:

we know that

Applying the law of sines in the triangle ABC

\frac{sin(A)}{a}=\frac{sin(B)}{b}

substitute the given values

\frac{sin(45\°)}{7}=\frac{sin(40\°)}{b}

b=\frac{7}{sin(45\°)}sin(40\°)\\\\b=6.4\ units

What term can you add to 5/6x-4 to make it equivalent to 1/2x-4?
patriot [66]

\frac{-1}{3}x can be added to \frac{5}{6}x-4 to make it equivalent to \frac{1}{2}x-4.

Step-by-step explanation:

Let,

y be the term that can be added to given fraction.

Therefore;

(\frac{5}{6}x-4)+y=\frac{1}{2}x-4

Subtracting \frac{5}{6}x-4 from both sides to find y

(\frac{5}{6}x-4)-(\frac{5}{6}x-4)+y=\frac{1}{2}x-4-(\frac{5}{6}x-4)\\\\\frac{5}{6}x-4-\frac{5}{6}x+4+y=\frac{1}{2}x+4-\frac{5}{6}x+4\\\\y=\frac{1}{2}x-\frac{5}{6}x\\\\y=\frac{3-5}{6}x\\\\y=\frac{-2}{6}x\\\\y=\frac{-1}{3}x

\frac{-1}{3}x can be added to \frac{5}{6}x-4 to make it equivalent to \frac{1}{2}x-4.
