Answers:
∠A=45° & ∠B=45°
Step-by-step explanation:
In triangle ABC, all angles are less than 180° but their sum is 180°
For the trigonometric statements
sin(A)=cos(B)
sin(B)=cos(A)
These are true when these angles that are A and B are equal and on these angles the sin and cos value must be same.
Hence, both angles are of 45°

boo divide 16.17 by 7 to find 1 pound, i dont get y every time i refresh ur questions pop up looooool XD
Answer:
16
Step-by-step explanation:
The ratio fo the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
In a 30-60-90 triangle, the length of the short leg is the length of the long leg divided by sqrt(3).
The length of the short leg is 8 cm.
The length of the hypotenuse is twice the length of the short leg.
g = 2 * 8 cm = 16 cm
6x + x + x - 5 - 2 = 8 + 2x + x
combine like terms
8x -7 = 8 +3x
subtract 3x from each side
5x -7 = 8
add 7 to each side
5x = 15
divide by 5
x=3
Answer: 8x -7 = 8 +3x
x=3
