Answer:
Angle D equals 80 degrees.
Since both triangles and angles are congruent, you can use triangle ABC to find the measure of CDE.
ABC has to equal 180 degrees so that means that 30 + 70 + <B = 180
add: 100 + <B = 180
Subtract <B = 80
Angle B equals 80 degrees which also means that Angle D equals 80 degrees.
Answer:
The Scarecrow got it wrong.
Step-by-step explanation:
1. The Pythagoras theorem does not apply to every isosceles triangle. It only applies to a triangle that has one of its sides as a right angle i.e. 90 degrees.
2. The Pythagoras theorem deals with squares of sides not square roots of sides.
3. Pythagoras theorem does not state that the square of any side is equal to the sum of the remaining two. Instead, it states that the square of the hypotenuse of a right angled triangle is equal to the sum of the square of the remaining two sides.
4. The Pythagoras theorem does not mention anything about an isosceles triangle. It deals only with Right angled triangles.
Answer:
y = 1/2x + 2
Step-by-step explanation:
y = mx+b, where m is the slope, b is y-int, and y and x are variables.
Step 1: find the y-int: 2. Using this you can out rule C and D.
Step 2: find the RISE/RUN: 1/2. This is your slope.
Step 3: fill in your equation.

You can dispose a number 
of elements in a matrix-like formation with 
shape if and only if 
and 
both divide , and also 
.
So, we need to find the greatest common divisor between 
and 
, so that we can use that divisor as the number of columns, and then.
To do so, we need to find the prime factorization of the two numbers:
So, the two numbers share only one prime in their factorization, namely 
, but we can't take "too many" of them: has "three two's" inside, while has "five two's" inside. So, we can take at most "three two's" to make sure that it is a common divisor. As for the other primes, we can't include 
nor 
, because it's not a shared prime.
So, the greater number of columns is 
, which yield the following formations:
