Answer:
The value of the exterior angle is 
Step-by-step explanation:
we know that
The sum of the interior angle plus the exterior angle is equal to 
, because are supplementary angles.
Let
x-----> the measure of the exterior angle
so
solve for x
Answer:
The 4 interior angles in the square are each 90 degrees. The four angles formed by the intersection of the 2 diagonal lines are each 90 degrees. The rest of the angles <PQT, <RQT, etc. Are all 45 degrees.
Answer:
The square cake is has a larger area by about 40.73 square inches
Step-by-step explanation:
Find the area of the top of each cake.
The square cake has an area of 81 sq inches, ( length x width = Area, the
length is 9)
The round cake has an area of 16π, which is about 50.27 square inches
(A = πr², here r is 4, radius is half the diameter)
81 - 16π = 81 - 50.27 = 40.73 square inches
Answer: A
Step-by-step explanation:
The first thing we need to do is to make sure our equation is in standard form. The given equation is not in standard form.
3x²-2x=0
Now that the equation is in standard form, we can find our A, B, C to see which quadratic equation is correct.
A=3
B=-2
C=0
We can automatically eliminate D because the first value is -3 when it is supposed to be -(-2). Also, the denominator is supposed to be 2a. We know that A=3. The denominator should be 2(3), not 2(-2).
Next, we can eliminate B and C. For the 4ac, we know it has to be 4(3)(0) because A=3 and C=0. B and C have given 4(3)(2) and 4(3)(1), respectively. This does not match A=3 and C=0.
Therefore, A is the correct answer.
