Answer:
45.7°
Step-by-step explanation:
- area of a triangle= 180°
- so,180- 88•6=91•4
- since the congruent angles are equal,you will divide 91•4 by 2
- 91•4÷2=45•7
- ans=45•7°
Answer:
The greatest number of displays that can be built using all the boxes are
(Using blue boxes and yellow boxes for each display).
Step-by-step explanation:
In order to answer the question, the first step is to divide the number of blue boxes and yellow boxes and look for a common ratio ⇒
This means that we have a ratio for blue boxes and yellow boxes.
We find that each display will have 5 blue boxes and 7 yellow boxes.
To find the greatest number of displays that can be built we can do the following calculation
Or
(We can divide the number of blue boxes by its correspond ratio number or the number of yellow boxes by its correspond ratio number)
In each cases the result is 13 displays.
The answer is 13 identical displays
Let us say that:
K = age of Kristen
B = age of Ben
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
So Kristen is 20 while Ben is 12.
It’s A. 38! You divide the diameter in half and use the radius to find the area of the circle
