Answer:
4/5
Step-by-step explanation:
The cosine of the angle is found as the ratio of adjacent to the hypotenuse.
To find it first find the sin 45 = √8/ x. This is equal to 4.
sin 45 = √8/ x
x = √8/ sin 45
x = 4
This means the triangle FHE has side lengths 3, 4, and 5.
The cosine of FHE will be FH / HE. This is 4/5.
The length of XZ is likely 8 i think since they are in that order, but idk. sorry if im wrong, and i hope this helped ):
Answer:
(-5,17) is a solution to the equation
Step-by-step explanation:
The equation is y = -2x+7
Substitute the values of x=-5 and y =17 into the equation and see if it is true
17 = -2(-5) +7
17 = 10+7
17=17
This is true so (-5,17) is a solution to the equation
Since the surface area of a prism is
A = 2lw + 2lh + 2wh
then the surface of the 1/3 scale key chain will be:
A = 2( l / 3 )( w / 3 ) + 2 ( l / 3 )( h / 3 ) + 2( w / 3 )( h / 3)
A = (2/9) ( lw ) + ( 2 / 9 ) ( lh ) + ( 2/9 ) ( wh)
A = ( 1 / 9 ) ( lw + 2lh + 2wh)
so the ratio <span>of the key chain to the book is 1/9</span>
Answer:
Each state also had a governor. This official was elected either by the legislature or by the citizens. The governor’s job was to carry out the laws. Finally, each state had courts. Judges in the courts decided what the laws meant and how to apply them to each new situation.
