Answer:
cos B = 
tan B = 
sin B = 
Step-by-step explanation:
In the right triangle, there are three sides and 2 acute angles
- Hypotenuse ⇒ the opposite side of the right angle
- Leg1 and Leg 2 ⇒ the sides of the right angle
The trigonometry functions of one of the acute angles Ф are
- sin Ф = opposite leg/hypotenuse
- cos Ф = adjacent leg/hypotenuse
- tan Ф = opposite leg/adjacent leg
In Δ ACB
∵ ∠C is the right angle
∴ AB is the hypotenuse
∵ AC is the opposite side of ∠B ⇒ leg1
∵ CB is the adjacent side of ∠B ⇒ leg2
→ By using the ratios above
∴ cos B =
, tan B =
, sin B = 
∵ CB = 7, AB = 25, AC = 24
∴ cos B = 
∴ tan B = 
∴ sin B = 
8 cm and 9 cm is the correct answer
Since EF=FG, you can set 6x - 10 = to 3x + 11

Then add like terms

so,

Now you can divide by 3 to get

:)
then put it back into


so,
Answer:
11 and 7.
Step-by-step explanation:
7 + 11 = 18
7 times 2 is 14 and 14 + 11 = 25
