If ABCD is a square what is m< AEB
A) 30°
B) 45°
C) 60°
D) 90°
Answer:
90
Step-by-step explanation:
The angle of AEB is 90 degrees, took the test and got it correct!
The measure of m<AEB is 90 degrees
Squares and triangleFrom the given square, the triangle AEB is a right triangle.
A right triangle has one of its angles to be 90 degrees.According to triangles AEB, m<EAB = m<ABE = 45 degreesm<AEB = 180 - (45+45)
m<AEB = 180 - 90
m<AEB = 90 degrees
Hence the measure of m<AEB is 90 degrees

Write your answer using a percent sign (%).
Answer:
50%
Step-by-step explanation:
45 is half of 90. A percent is out of 100. So when you split 100 in half, it equals 50. The answer is 50%. Glad I could help!

what is the area of a 3 and a quarter inch circle?
Answer:
33.2in²Step-by-step explanation:
to find area we have to find redious first sor=d/2therefore
[tex]r = \frac{3 \frac{1}{4} }{2} [/tex]
[tex]r = \frac{ \frac{13}{2} }{2} [/tex]
[tex]r = \frac{13}{2} \div 2[/tex]
[tex]r = \frac{13}{4} [/tex]
[tex]area \: of \: a \: circle \: = \pi {r}^{2} [/tex]
[tex] = \pi (\frac{13}{4} ) ^{2} i {n}^{2} [/tex]

Answer:
x = 20y = 10Step-by-step explanation:
The angle marks show that ΔRST is isosceles, so RT = RS. They also show ΔRTU to be equilateral, so UT = RT.
UT = RS
x -5 = 15
x = 20 . . . . . . add 5
__
ΔRTU is equilateral, so ∠RTU is 60°. The angle marked 3y° is complementary to that.
3y = 30
y = 10 . . . . . divide by 3

The graph of which function has an amplitude of 3 and a right phase shift of ?
Answer:
The first one
Step-by-step explanation:
The amplitude is usually the first number (for example, in this equation, the 3). Then you also know that the right or left shift depends on the addition or subtraction sign. Usually, the subtraction sign means to the right and the addition sign means to the left.
We have that the graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex] is
[tex]3sin2(x+\phi)[/tex]
The Correct option is D
From the Question we are told that
A graph has
Amplitude of 3
Phase [tex]\phi= \frac{\pi}{4}[/tex]
Generally the equation for the Wave Equation is mathematically given as
[tex]Asin(kx-wt+\phi)[/tex]
Therefore the Equation for this particular wave is
[tex]3sin2(x+\phi)[/tex]
Hence
The graph of which function has an amplitude of 3 and a right phase shift of [tex]\phi= \frac{\pi}{4}[/tex] is
[tex]3sin2(x+\phi)[/tex]
The Correct option is D

Sum of two numbers = 15 (Addition)
Difference of two numbers =3 (Subtraction)
Find the two numbers.
What is the product of those two numbers? (Multiplication)
Answer:
The numbers are x= 9 and y =6
The product of two numbers
x y = 9 × 6 = 54
Step-by-step explanation:
Step(i):-
Let x and y are two numbers
Given that the sum of two numbers
x + y = 15 ..(i)
Given that the difference of two numbers
x - y = 3 ..(ii)
adding (i) and (ii) , we get
x + y + x -y = 15 +3
2 x = 18
x =9
Step(ii):-
Substitute x = 9 in equation (i) , we get
x + y = 15
9 + y = 15
y = 15 - 9
y = 6
Final answer:-
The numbers are x= 9 and y =6
The product of two numbers
x y = 9 × 6 = 54

46 = -6t -8
Urgent. Please answer ASAP. Thanks guys!
Answer:
n= -9, t= -9
Step-by-step explanation:
1) -1/3(n+15)=-2
-1/3×n+-1/3×15=-2
-1/3×n -5= -2
-1/3 n-5+5= -2+5
-1/3×n=3
3/-1×-1/3×n=3/-1×3
n= -9
2) 46 = -6t -8
−6t−8=46
−6t−8+8=46+8
−6t=54
Divide both sides by -6
t=-9

Steps to derive correct answer :Diameter of the stained glass window Joey needs = 3.5
Area of the window = quantity of glass Joey needs
Area of the window :
