Answer:
< 1 = 125 degrees
< 2 = 55 degrees
< 3 = 125 degrees
< 4 = 55 degrees
< 5 = 125 degrees
< 6 = 55 degrees
< 7 = 125 degrees (given)
< 8 = 55 degrees
Step-by-step explanation:
1 and 3 are equal because they are vertical angles, therefore proving their congruence.
7 and 1 are equal because they're alternate exterior angles, which are congruent.
2 and 4 are vertical, which is congruent.
5 and 7 are vertical.
6 and 8 are vertical.
<span><span>To find the area of a rectangle, multiply the length by the width.
The formula is:</span><span>, where is the area, is the length, is the width, and · means multiply.
Because 112 = 14 </span></span>· 8 , then, the width of the rectangle is 8 cm;
The answer is B.
Answer:
the answer is B
Step-by-step explanation:
Answer:
x = 8,
Step-by-step explanation:
.
for it is a denominator. Multiply both sides with the product of the two denominators: 
:
.
.
Multiply both sides by one over the coefficient of x:
.
.
Step-by-step explanation:
your teacher even wrote all the formulas there.
you have all numbers.
so, all that is left is to take the calculator and type things in.
so, what was your problem here ?
I cannot tell you much more than what is written in your question already.
the only thing : the radius (needed in the formula) is half of the diameter.
so,
V = 4/3 × pi × r³ = 4/3 × pi × (16/2)³ = 4/3 × pi × 8³ =
= 4/3 × pi × 512 = 2048/3 × pi = 2,144.660585... ft³ ≈
≈ 2,144.7 ft³
