Find the value of the lettered angles in each of the following ( see image ).
Please show workings.
The only given angles are 56° in the first circle and 65° in the second circle.
Note : O indicates the center of the circle is above it.

Answer:
Question 1
h = 56° as alternate interior angles (the diameter is the transversal)f = 90° as opposite to the diameterg = 90° - 56° = 34° as complementary angle in right triangleQuestion 2
i = 65° as the same arc is interceptedi + j = 90° as opposite to diameterj = 90° - i = 90° - 65° = 25°Related Questions

Claire's backyard is in the shape of a rectangle and has a length of 19.5 feet. It cost her $945 to fence in the yard. If fencing costs $15 per foot, what is the width of Claire's backyard?
Answers
Answer:
Step-by-step explanation:
You need to know the formula for the perimeter of a rectangle. We won't use it right away, but it is pertinent information.
P = 2 ( l + w )
Now, we know that the fencing costs $15.00 per foot, and that the length is 19.50 feet.
We first need to find the price of one "length" side of the fence.
To do this, multiply 19.50 by 15.00
19.50 x 15.00 = 292.5
Next, we look at the perimeter equation to see what we can plug in where.
P = 2 ( l + w )
We can put in the total price of the fencing for the yard as P, and the amount of one length side of the fence as l.
945.00 = 2 ( 292.5 + w )
And now, we simply solve for w.
945.00 ÷ 2 = ( 2 ( 292.5 + w ) ) ÷ 2
472.5 = 292.5 + w
472.5 - 292.5 = 292.5 + w - 292.5
w = 180
It costs $180 for one "width" side of the fence.
To find out how many feet that is, we do the opposite of what we did with the length. Instead of multiplying by $15.00, we divide by $15.00
$180.00 ÷ $15.00 = 12
The width of Claire's backyard is 12 feet.

how do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3
Answers
Answer:
Step-by-step explanation:
exponents raised to a - power is an inverse function probably not the right word
a^-b = 1/(a^b) example 4^-2 = 1/(4^2) = 1/16
so (7^-1)^-1 is a double inverse which is back to the original number 7
inverted 7 twice
(7^-1)^-1 = (1/7)^-1 = 1/(1/7) = 7 trust me or use your calculator
since the coeffients are the same just add the powers... some exponent rule
5^2 * 5^4 * 5^-3 = 5^(2+4-3) = 5³
here is it written out
5^2 * 5^4 * 5^-3 = 5² × 5^4 × 5^-3 = (5×5) × (5×5×5×5) × (1/5×1/5×1/5)
5×5 × 5× (5×5×5 × 1/5×1/5×1/5) (5×5×5 × 1/5×1/5×1/5) = 1
5×5×5 = 5³

Rachel is selling gift cards to raise money for her swim team. Each gift card costs $25.00. If c represents the number of gift cards she sells, , which equation models the amount of money she could raise?
Let t represent the total amount collected
Each gift card costs $25.00.
If c represents the number of gift cards she sells
The equation that models the amount of money she could raise is written as:
t = $25 × c

He would factor out 4(x+5)
Step-by-step explanation:
You can't do much until the 4(x+5) is factored out.
Once it is then it'd be 3x-8=4x+20
Then you subtract 3x on both sides and subtract 20 on both sides.
You'd be left with -28=x
