Answer:
CD = 3
Step-by-step explanation:
If B is the midpoint of AC, AB and BC are equal. BC = 2, so that means AB = 2. This means AC = 4. If the whole line = 7, then CD, the only segment we don't know, = 7 - 4, which equals 3.
answer is c because if it's not a and b then the only answers will be c and d and d is the same as the number so it's c
The value of the digit 2 ten times greater in 5426 is 400.
Step-by-step explanation:
The given is, the value of the digit 2 in 5426 is 20.
Step:1
Let, Y
where, Y is the value of the digit 2 ten times greater.
Step:2
Now, Y= 10X
( Y=10X is formed because of ten times greater than)
where, X is the value of digit 2 in 5426.
Step:3
Substitute,
X value in the equation
Y=10×20
Y=200
Result:
The value of 200 is digit 3.
So, the answer for digit 2 ten times greater is 400.
Answer:
a = 25 m²
b = 5 m
c = 7.94 m
d = 35.73 m²
Code: H I A B
Step-by-step explanation:
<u>Formulae</u>
Pythagoras’ Theorem: 
(where a and b are the legs, and c is the hypotenuse, of a right triangle)
Area of a square = x² (where x is the side length)
------------------------------------------------------------------------------------------------------
Assuming that all the quadrilaterals are squares.
Side length of blue square with area 16 m² = √16 = 4 m
Side length of yellow square with area 9 m² = √9 = 3 m
Use Pythagoras' Theorem to find the <u>length of b</u>:




Now we have found length b, we can find <u>area a</u>:

Side length of purple square with area 144 m² = √144 = 12 m
Side length of green square with area 81 m² = √81 = 9 m
Use Pythagoras' Theorem to find the <u>length of c</u>:





Now we have found length d, we can find <u>area d</u>:

Code: H I A B
Answer:
The other measure is 161 degrees
Step-by-step explanation:
because complementary means that the angles equal 180 so 180-19 gives you 161 degrees
