A is correct because 1 and 3 are vertical angles.

B is correct because there are 180 degrees in a triangle. 180-65-55 = 60. Angle 2 is vertical to the third angle, so angle 2 equals 60.

C is incorrect because it is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 ≠ 60.

D is correct because 3 is an exterior angle. Exterior angles are equal to the sum of the two isolated interior angles. 65 + 55 = 120.

In review, A, B, and D are correct.

I hope this helps you =)

The difference of the squares of two positive consecutive even integers is 44 find the integers use the fact that if X represent

TiliK225 [7]

Answer:

The 2 integers are 10 and 12

Step-by-step explanation:

Translate it into english

"The difference (some subtraction) of the squares of two positive consecutive integers ( $x^2$ and $(x+2)^2$ ) is (=) 44 (44)"

this means the following:

$(x+2)^2-x^2=44$

solve for x to find the smaller integer

first, expand

$(x^2+4x+4)-x^2=44$

$x^2+4x+4-x^2=44$

$4x+4=44$

$4x=40$

$x=10\rightarrow x+2=10+2=12$

The 2 integers are 10 and 12

mestny [16]

Answer:

$123,456,789 = 1.23456789\times 10^8$

Step-by-step explanation:

It is required to find the value of the missing exponent in the below value i.e.

$123,456,789 = 1.23456789\times 10^x$

Let the exponent is x.

Any number can be written in the scientific notation as :

$N=a\times 10^b$

a is a real number

b is any integer

In this case, the decimal is applied before 8 numbers. It means that the value of x is 8.

The theoretical probability that a man will have some form of color blindness is 8%.

Number of men in group = 700

Number of men with color blindness in a group of 700 men

If you have a group of 700 men, 56 will be color blind

Croscheck 8% of 700 is 56
