Answer:

Step-by-step explanation:
<em>Hey there!</em>
Well using the given ratio,
3:4
And the area of the small shape we need to do,
72*72 = 5184
Now we can make the following fractions,
= 
Now we can solve,
3*x = 3x
4 * 5184 = 20736
3x = 20736
20736 / 3
x = 6912
So the area of the bigger shape is 6912 units^2

Answer:
Step-by-step explanation:
Complementary angles mean two two angles sum with equal 90 degrees. Therefore you would need to create an equation to solve for the value of x.
4x+3x+13=90
-13 -13
7x=77
/7 /7
X=11
Now plug in the value of x.
A=4(11) B=3(11)+13
A=44. B=33+13
B=46
Angle a is the smaller angle and measures at 44°
Answer:
A
Step-by-step explanation:
A parcent as a fraction would be /100. So the answer would not be C or D. And since it isn't B, the answer is only A
Answer: Twelve fifth of an Hour
Step-by-step explanation: a whole is represented by 1
1/3=4/5hours
Whole room 1 =4/5 ÷ 1/3
=4/5×3/1
=4×3/5
=12/5
That's twelve fifth of an hour
