Answer:
1st pic) 17.8
2nd pic) 16.8
3rd pic) 9.1
4th pic) 13.5
Step-by-step explanation:
1st pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]
(write equation) Cos 27 (cos 27 = 0.89) = [tex]\frac{x}{20}[/tex]
(new equation) 0. 89 = [tex]\frac{x}{20}[/tex]
(multiply 20 on both sides) 0.89 x 20 = [tex]\frac{x}{20}[/tex] x 20
(solve) 17.8 = x
2nd pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]
(write equation) tan 40 (tan 40 = 0.84) = [tex]\frac{32}{x}[/tex]
(new equation) 0.84 = [tex]\frac{32}{x}[/tex]
(multiply 32 on both sides) 0.84 x 20 = [tex]\frac{32}{x}[/tex] x 20
(solve) 16.8 = x
3rd pic: [tex]cos = \frac{adjacent}{hypothenuse}[/tex]
(write equation) cos 55 (cos 55 = 0.57) = [tex]\frac{16}{x}[/tex]
(new equation) 0.57 = [tex]\frac{16}{x}[/tex]
(multiply 16 on both sides) 0.57 x 16 = [tex]\frac{16}{x}[/tex] x 16
(solve) 9.1 = x
4th pic: [tex]tan = \frac{adjacentx}{hypothenuse}[/tex]
(write eqaution) tan 42 (tan 42 = 0.90) = [tex]\frac{x}{15}[/tex]
(new equation) 0.90 = [tex]\frac{x}{15}[/tex]
(multiply 15 on both sides) 0.90 x 15 = [tex]\frac{x}{15}[/tex] x 15
(solve) 13.5 = x

Answer:
The shorter leg, s, is the geometric mean between h and m
The longer leg, b, is the geometric mean between h and n
Step-by-step explanation:
By the right triangle geometric mean theorem, we have;
The altitude of a right triangle, 'h', which intersects with the hypotenuse side of the right triangle at a point such that it creates two segments, 'a' and 'b' on the hypotenuse side , then we have;
h = √(a·b)
Therefore, we have;
Description [tex]{}[/tex] Proportion
The altitude of ΔAYES is the geometric mean between m and n [tex]\dfrac{m}{a} =\dfrac{a}{n}[/tex]
a² = m·n → a = √(m·n)
The shorter leg, s, is the geometric mean between h and m [tex]\dfrac{m}{s} =\dfrac{s}{h}[/tex]
s² = m·h → s = √(m·h)
The longer leg, b, is the geometric mean between h and n [tex]\dfrac{n}{b} =\dfrac{b}{h}[/tex]
b² = n·h → s = √(n·h)

A hawk takes flight from a mountain peak and flies 800 meters west. Then it takes a turn and flies 200 meters south. What is the distance and direction of the hawk from the mountain peak?
Answers
Answer:
the hawk has flow 824.62 meters southwest of the mountain peak.
Step-by-step explanation:
In order to find the distance we need to use the Pythagoras theorem
d^2 = 800^2 + 200^2
d= 824.6 m
we can find the direction by using the eq for a tangent
he opposite side is 200 m and the adjacent side is 800m
tan theta = opposite / adjacent
theta = arc tan (800/200)
The hawk is at a distance of 824.6m flying at an angle 76 degrees NE of the mountain peak.
The final location will be southwest of the mountain peek.
a2+b2=c2
a = 200
b= 800
c = √(2002+8002) = 824.62
So the hawk has flow 824.62 meters southwest of the mountain peak.

Answers
Answer:
For #5: There are 3 children and 4 adults.
Step-by-step explanation:
Let x= number of children
y= number of adults
y = x + 1
x + y = 7
x + (x+1) = 7
x + x + 1 = 7
2x + 1 = 7
2x = 7 - 1
2x = 6
x = 6/2
x = 3
y = x + 1
y = 3 + 1
y = 4
Therefore, the number of children is 3 and the adults are 4.

Jet had $63 to spend at Pet Smart. She spent 2/7 of her money on dog bones and the rest on squeaky toys to destroy. How much money she spend on the squeaky toys? (Just type the answer with the proper label, no complete sentence needed).
Answers
Answer:
She spent 45 dollars on squeaky toys.
Step-by-step explanation:
If we divide 63 by 7 we would get 9, then if we multiply that number by 2 for the bones, we are left with 5/7, finally if we multiply the 5 by 9 you would get 45, or 45 dollars.

Find the area of the figure below
Please help
Answers
============================================================
Explanation:
Rotate the triangle so that the side 17 cm is completely horizontal and the triangle is pointing upward. The 10.3 cm portion is the height. The base and height are always perpendicular to one another.
Area = (base*height)/2
Area = (17*10.3)/2
Area = 87.55 square cm
The sides 12 cm and 15 cm are not needed at all. They might have been put in there as a distraction.
