Answer:

Option A. 43.5\ in^{2}  

Step-by-step explanation:

we know that

The area of a trapezoid is equal to

A=(1/2)(b1+b2)h

we have

b1=1\frac{1}{4}\ ft

b2=14\ in

h=3\ in

Convert feet to inches first

Remember that

1\ ft=12\ in

so

1\frac{1}{4}\ ft=\frac{5}{4}\ ft=12*\frac{5}{4}=15\ in

substitute in the formula

A=(1/2)(15+14)3=43.5\ in^{2}

A square has a diagonal of 44in. I want to frame the picture, how many inches of frame do I need
dimaraw [331]

The square has a 44-inch diagonal.

The pythagorean equation must be used to obtain the hand.

Diagonal (d) ^ 2 = side^2 + side ^ 2

Diagonal (d) ^ 2 = 2side (s)^2

d^2 = 2s^2

44^2 = 2s^2

1936 = 2s^2

2s^2 = 1936

s^2 = 968

s = 31.11 inches

The length of the side is around 31 inches

Perimeter = 4*s

Perimeter = 4 * 31

Perimeter = 124 inches

As a result, you will need a total of 124 inches to frame the rectangle.

Hope this helps you!!

What is m CDJ? <br>please help me I'm super confused.​
Citrus2011 [14]

Answer:

34 degrees.

Step-by-step explanation:

Assuming AK is a straight line and being shown angle JDK is right and 90 degrees it can be stated that 4x + (3x-8) = 90 degrees.

Drop the parentheses and get 7x - 8 = 90.

Add 8 to both sides 7x = 98.

Divide both sides by 7, x = 14.

Plug that x value into (3x-8), [3(14)-8] = 34 degrees.
