Step-by-step explanation:

y = 3x + 5 \\ 2x + 4y = 6 \\ subsitution \\ 2x + 4(3x + 5) = 6 \\ 2x + 12x + 20 = 6 \\ 14x =  - 14 \\ x =  - 1 \\ y = 3x + 5 \\ y =  - 3 + 5 \\ y = 2

R = 850 cm, s = 250 cm and t=940 cm. Find the measure of ZS tothe nearest 10th of a degree
faust18 [17]

To find the measure of the s angle que are going use the cosine law because we know all the sides of the triangule:

s² = r² + t² - 2*r*t * cos(S)

Then solve the equation

s² -r² - t² = -2*r*t * cos(S)

arccos ((s² -r² - t² /-2*r*t)) = S

arccos (((250)² -(850 cm)²-(940 cm)² /(-2* 850 cm*940 cm) = S

14.9 = S

round to the nearest 10th of a degree

15º = S

AM and AN are tangent to circle C. If AM measures 2.5 cm, what is the measure of AN?
Vera_Pavlovna [14]

The measure of AN form the given figure is 2. 5cm. Option D

<h3>How to determine the length</h3>

It is important to note that if from one external point, two tangents are drawn to a circle then they have equal tangent segments.

We have that,

AM ≅ AN

so, if AM  measures 2. 5cm

AN measures 2. 5cm

Thus, the measure of AN form the given figure is 2. 5cm. Option D
