Answer:
1.) x = 50 2.) x = 70
Step-by-step explanation:
These angles are complementary angles meaning the angles add up to 90°. Therefore, we can set up equations to solve for the variables.
1.)
x + 40 = 90
x = 50
2.)
x + 20 = 90
x = 70
The area of the square will be 640 sq cm.
Step-by-step explanation:
Given,
Number of strip = 4
Length (l) of each strip = 40 cm
Width (b) of each strip = 4 cm
To find the area of the inner square.
Formula
The area of rectangle = l×b
If the area of a square is A, each side will be √A
Now,
Area of each strip = 40×4 sq cm = 160 sq cm
Area of 4 strips = 160×4 sq cm = 640 sq cm
Hence,
The area of the square will be 640 sq cm.
Answer:
42 or B
Step-by-step explanation:
So the top triangle is similar to the whole triangle by AA similarity. It has a ratio of 1:2. So 4x+2:4x+44 is 1:2. So 8x+4=4x+44. Simplifying, we get 4x=40 or x=10 So 4x+2=42
Answer:
21 3/4
Step-by-step explanation:
find the lowest and highest numbers
10 1/4 and 32
take 10 1/4 and subtract it from 32
21 3/4
