Answer:
cos(E)=0.8
Step-by-step explanation:
cos(E)=adjacent/hypotenuse
Using a common pythagorean triple, we can find that side GE is 30 (18^2+24^2=30^2)
Then we just get cos(E)=24/30, which is 0.8
Answer:
7.8
Step-by-step explanation:
The diameter is the full length across a circle. The radius is always half the diameter. if you divide 15.6 by 2 (to get half), we get 7.8. If this does not answer the question, let me know so I can edit
What does it want you to do
Answer:
see the explanation
Step-by-step explanation:
we know that
point B(-6, 1) is translated to B'(-3,-2)
step 1
The rule of the translation is
(x,y) -------> (x+a,y+b)
substitute
B(-6,1) -------> B'(-3,-2)
step 2
Write the equations
-6+a=-3
-2=1+b
step 3
Solve each equation
-6+a=-3 ------> a=-3+6 -----> a=3
-2=1+b ------> b=-2-1 ------> b=-3
step 4
Write the rule of translation
(x,y) -------> (x+3,y-3)
That means ------> The translation is 3 units at right and 3 units down
