GarryVolchara [31]3 years ago
3 0

Answer:

65.4

Step-by-step explanation:

In any right triangle, the cosine of an angle is equal to its adjacent side divided by the hypotenuse, or longest side, of the triangle.

Therefore, we have:

\cos 61^{\circ}=\frac{y}{135},\\t=135\cos 61^{\circ}=65.4492987333\approx \boxed{65.4}

Given the two points (-1,-4) and (2,5): a. Find the slope between these two points
Dvinal [7]
Easy, using \frac{y1-y2}{x1-x2} to find the intercept:

\frac{-4-5}{-1-2}=

\frac{-9}{-3}=3

This is your slope. m=3

To find y=mx+b form

-4=3(-1)+b

-4=-3+b

-1=b

y=3x-1 in y=mx+b form

AB<br> Round your answer to the nearest hundredth.<br> А<br> 50°<br> 6<br> 12<br> B
Nezavi [6.7K]

Answer:

h = 7.832

Step-by-step explanation:

This is a right angled triangle so, taking 50 as reference angle,

hypotenuse = ?

perpendicular = 6

The ratio for p and h is given by

Sin 50 = p/h

Sin 50 = 6 /h

h = 6 / Sin 50

h = 7.832
