elena55 [62]

Answer:

x = 29

Angle A = 46.4°

Angle B = 43.6°

Step-by-step explanation:

Since it is a right angle triangle, we can find x from pythagoras theorem;

x = √(20² + 21²)

x = √(400 + 441)

x = √841

x = 29

Using trigonometric ratios we can find angles A and B.

Opposite is 20

Adjacent is 21

Thus; opp/adj = tan B

20/21 = tan B

B = tan^(-1) 0.9524

B = 43.6°

Sum of angles in a triangle is 180°. Thus;

A = 180 - (90 + 43.6)

A = 46.4°

Would it be 4? Or would I do 1 divided by four
Lunna [17]

Answer:

k = 4

Step-by-step explanation:

The graph represents y and x in direct proportion with equation

y = kx ← k is the constant of proportionality

To find k use the point (1, 4), that is x = 1, y = 4

k = \frac{y}{x} = \frac{4}{1} = 4

What is the equation of a line that has a slope of 0 and passes through (5, −2)?
kumpel [21]

y=-2

Step-by-step explanation:

if line has zero slope (b) it means that b is undefined.

if x=0 y=-2 because line has no slope. so b=-2

y=-2
