Answer:
Cos A = 24/25 & Tan A = 7/24
Step-by-step explanation:
See the attached figure.
Construct a right triangle and sign one angle as A
So, Sin A = opposite/hypotenuse = 7/25
∴hypotenuse = 25 and opposite = 7
∴ adjacent = √(25² - 7² ) = √576 = 24
∴ Cos A = adjacent/hypotenuse = 24/25
And
Tan A = opposite/adjacent = 7/24
Answer:
D
Step-by-step explanation:
I just plugged in the numbers
Change 3/4 to 0.75 and then plug in 8
0.75(8 + 12) = 15
0.75(20) = 15
15 = 15
Hope this helps :)
Idk good luck hope you get the right answer
