Which equation shows a correct relation for triangle RSQ?

Mathematics
1 answer:
son4ous [18]3 years ago
4 0

Answer:

sinQ=cosR

Step-by-step explanation:

First we need to find out the measure of ∠R.

The sum of all the angles in a triangle add up to 180. Therefore:

∠Q+∠R+∠S=180

66+∠R+90=180

∠R=180-156

∠R=24°

Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.

sinQ=cosR

sin66=cos24

0.9135454576=0.9135454576

So the second equation is the correct relation.

26 out of 48 books are small. What percentage of the books are small?
Paraphin [41]

Answer:

54.16%

Step-by-step explanation:

The percentage of books that are some is 54.16 %

In order to find that answer you would have to calculate the total number of small books (26) over the total number of all of the books (48).

The equation would be 26/48=0.5416 however Multiply that answer by 100 and you would get 54.16% and if you want to round to the nearest whole number it would just be 54%

If the sixth term of a sequence is 128 and the common ratio is 2, then what is the first term?
Lady bird [3.3K]
Geometric progresión:
we can calculate any term, using this rule:
 
an=a₁*r^(n-1)
a₁=the first term
r=the common ratio


a₆=128
r=2

an=a₁ * r^(n-1)
128=a₁ * 2⁶⁻¹
128=a₁ * 2⁵
128=a₁ * 32
a₁=128/32=4

Solution: a₁=4

a tree was 62 inches tall. Three years later, it was 101 inches tall. What was the percent increase, to the nearest hundredth, o
nignag [31]

Answer:

63% increase.

Step-by-step explanation:

You don't really need to do anything because it's probably a 63% increase as 101 is close to 100 already. If you'd like:

\frac{101-62}{62} *100=

\frac{39}{62} *100=

62.903225806451612903225806451613≈

63%
