For an angle (theta) with the point (5, -12) on its terminating side, what is the value of cosine?

padilas [110]

we are given

(x,y)=(5,-12)

so, x=5 and y=-12

now, we can find r

$r=\sqrt{x^2+y^2}$

$r=\sqrt{5^2+(-12)^2}$

$r=13$

now, we can find cos

$cos(\theta)=\frac{x}{r}$

so, we get

$cos(\theta)=\frac{5}{13}$ ...........Answer

Find the angles of 22 and 24 thanks

netineya [11]

Answer:

22) 119

24) 15

Step-by-step explanation:

22) 61 + b = 180 <-- supplementary because on the same line

b = 119 <-- subtracted 61 from both sides

24) 87 + (6x + 3) = 180 <-- supplementary because on the same line

87 + 6x + 3 = 180 <-- take out parantheses

90 + 6x = 180 <-- add like terms

6x = 90 <-- subtracted 90 from both sides

x = 15 <-- solve for x by dividing 6 from both sides
