Find the cosine of both angle A and angle B.
2 answers:
We know that cos A=adjacent side angle A/hypotenuse adjacent side angle A=24 units hypotenuse=26 units cos A=24/26-----> 12/13 cos B=adjacent side angle B/hypotenuse adjacent side angle B=10 units hypotenuse=26 units cos B=10/26------> 5/13the answers are cos A=12/13 cos B=5/13 cot A=adjacent side angle A/opposite side angle A adjacent side angle A=24 units opposite side angle A=10 unitscot A=24/10------> cot A=12/5 cot B=adjacent side angle B/opposite side angle B adjacent side angle B=10 units opposite side angle B=24 unitscot B=10/24------> cot B=5/12
Cosine of an angle is the ratio of adjacent to hypotenuse. So, cos A = 24/26 = 0.923 Cos B = 10/26 = 0.3846

You just have to subtract four from each side to get x alone. The answer is x = -18
C)
you look at were the graph starts to decrease then look at the X-VALUE not the y-value
the x-val at the start of the decrease is -3 and at the end of it it is 2 therefor -3
x

They are about 400cm long just make sure u put that
Answer:
Step-by-step explanation:
y + 4 = -6(x - 7)
y + 4 = -6x + 42
y = -6x + 38
Answer:
Kirasent 16 and Ryan sent 96
Step-by-step explanation:
I got this because Kira is x-8 and Ryan is 4x. 4x-x-8=112 is equal to 5x=120. So x=24.Kira has 16 when plugging in x and Ryan has 96 because 4 times 24 is 96.
