Find the measure of two complementary angles, a and b, if m a = 7x + 4 and m b =4x + 9
VashaNatasha [74]
Complentary angles add to 90 degrees
a and b are complentary
a+b=90

a=7x+4
b=4x+9
so
7x+4+4x+9=90
combine like terms
11x+13=90
minus 13 both sides
11x=77
divide both sides by 11
x=7

m a =7x+4=7(7)+4=49+4=53
m b=4x+9=4(7)+9=28+9=37

angle a measures 53 degrees
angle b measures 37 degrees

Answer:

0=0

Step-by-step explanation:

Add zero

0+2=2

2=2

Subtract 2 from both sides of the equation

2=2

2−2=2−2

Simplify

Combine like terms

2−2=2−2

0=2-2s

or

0=2s-2

0=0

Answer 0=0

A deck of playing cards has four suits, with thirteen cards in each suit consisting of the numbers 2 through 10, a jack, a queen
vekshin1
Since order does not matter, you use a combination and not a permutation, so the first one is true, which means the second one is not true.
The probability of choosing two diamonds and three hearts can be represented by (13C2 * 13C3)/52C5, which is 0.0086, not 0.089, so the third one is not true.
The probability of choosing five spades and the probability of choosing five clubs are represented by the same thing, 13C5/52C5, which is roughly 0.0005, so the fourth one is not true but the fifth one is. So the answer is the first and fifth one.
