[Right Triangles Only] tan∅ = opposite over adjacent

Step-by-step explanation:

Step 1: Define

We are given a right triangle. We can use trig to find the missing side length.

Step 2: Identify Variables

POV from the angle measure

Angle = 23°

Opposite Leg = 25

Adjacent Leg = x

Step 3: Solve for x

Substitution [tangent]: tan23° = 25/x
Multiply x on both sides: xtan23° = 25
Isolate x: x = 25/tan23°
Evaluate: x = 58.8963
Round: x ≈ 58.9

I got 7x+4 because you distribute then add the X's and the whole numbers together.

If a varies directly as b, and a = 28 when b = 7, find b when a = 5.

Reika [66]

Answer: Option B.

$b=\frac{5}{4}$

Step-by-step explanation:

If a varies directly with b then when a increases b it also increases by a factor k.

Then we can write that

$a = kb$

We know that when a = 28 then b = 7. So

$28 = k * 7$

$k=\frac{28}{7}$

$k=4$

Therefore the equation of proportionality is:

$a=4b$

So when $a=5$ then:

$5=4b\\\\b=\frac{5}{4}$

Answer it guys pls idk how... you can also show the steps. For those who answer it all correctly I will give the brainliest answ

Answer:

essentially, in these problems, youre finding the square root of each number. the square root should be a decimal thats in between two other numbers, and those will be the integers that the value of the square root is between. unless the value is exactly a number and a half, it will be closer to one integer than the other. the work is below.

square root of:

59= 7.68

68= 8.246

78= 8.83

93= 9.64

104= 10.198

124= 11.14

33= 5.74

185= 13.6

215= 14.66

these are just the square roots. but, as you can see, each number is between two other whole numbers on a number line. So, just write down what those numbers are.

7.68 is between 7 and 8

8.246 is between 8 and 9

8.83 is between 8 and 9

9.64 is between 9 and 10

10.198 is between 10 and 11

11.14 is between 11 and 12

5.74 is between 5 and 6

13.6 is between 13 and 14

14.66 is between 14 and 15

so, we know thw numbers that each decimal is between, but we have to find which one each is cloest to. in order to do that, just know that if the decimal is more than .5 its closer to the larger number, and its its less than .5, its closer to thw smaller number.

7.68 is closer to 8

8.246 is closer to 8

8.83 is closer to 9

9.64 is closer to 10

10.198 is closer to 10

11.14 is closer to 11

5.74 is closer to 6

13.6 is closer to 14

14.66 is closer to 15
