Answer:

5.   8.49

6.   8.6

7.   B. Joe is taller than the tepee

Step-by-step explanation:

5 - formula for diagonal [tex]d= \sqrt{2} *s[/tex]   s= side length

So 1.4 times 6 = 8.49

6 - Pythagorean Theorem [tex]c= \sqrt{ a2+b2}[/tex]

So [tex]c= \sqrt{ 5 *2+7*2 }[/tex]   c = 8.6

7 -  Formula for height  [tex]h= \sqrt{ l^{2} - r^{2}[/tex]  l=slant height

So [tex]\sqrt{ 7^{2} - 4^{2}} =h\\\sqrt{ 49-16} = h\\h = 5.74\\5.74 < 6[/tex]That means Joe is taller

Answer:

The answers to your questions are :

5. Area of square = 36 , so (4 × X =36) . X=9

The formula used to find diagonal length = side × Rad2

9 × rad2 = 12.72

6 . Rad ( 25+49) = Rad(74) = 8.6

7. B is correct . He is taller than it .

Rad ( Slant height^2 - radius^2 ) = hight

hight = 5.7 .

Answer:

  A.  4.8 units

Step-by-step explanation:

Segment ZX can divide the figure into two right triangles. Then angle XZY is 136°/2 = 68°. The tangent relation tells you ...

  Tan = Opposite/Adjacent

  tan(68°) = XY/r

  r = 12/tan(68°) ≈ 4.848 ≈ 4.8

The radius of the circle is about 4.8 units.

Answer: 4.8 units

Step-by-step explanation:

Answer:

90+42+x = 180

132+x=180

x=180-132

x=48

Answer:

48 DEGREES

Step-by-step explanation:

First you need to find the other two angles : 42 + 90 = 132 ( the 90 comes from the little square like shape on the other angle).

So x = 180 - 132 = 48 ( we use 180 because it is the sum of interior angles of a triangle.

Answer:

36 cm^2.

Step-by-step explanation:

The area  is half the product of the lengths of its diagonals.

(PA)(LY) = (12cm)(6cm)

= 72 cm

72cm ÷2= 36 cm^2

Therefore the area is 36 cm^2

Answer:

-1/2x + 4.5

Step-by-step explanation:

Find out the slope by substituting the values in the formulas.

y2 - y1 / x2 - x1      6 - 2 / -3 - 5

-1/2

Now find the y-intercept.

y = mx + b

6 = -1/2 (-3) + b

6 = 3/2 + b

9/2 = b

Given:

The triangle is a right angle triangle

Height of triangle = 3 m

Hypotenuse of triangle = 5 m

To find:

Area of triangle

Steps:

To find the area of a triangle we have multiply the base and height of triangle into 1/2, but the figure doesn't show the measurements of the base, so we have to use Pythagoras theorem to find the third side this triangle is a right angle triangle.

A² + B² = C²

3² + B² = 5²

9 + B² = 25

      B² = 25 - 9

       B² = 16

         B = √16 = 4 m

Therefore the base length of the triangle is 4 m

Now we can find the area of the triangle

Area of triangle = (Base × Height)1/2

Area of triangle = (4 × 3)1/2

Area of triangle = 12 × 1/2

Area of triangle = 6 m²

Therefore the area of the triangle is B) 6 meters square

Step-by-step explanation:

First, you find the number of students eating either salads and sandwiches. Then, you add the number of students eating salads and sandwiches together. Finally, you will subtract that number from the 12 total students

Answer:

Sine, cosine and tangent formulas are used in RIGHT triangles. So you have one 90 degree angle and two acute angles that add up to 90 degrees (they are complimentary). So the cosine of one angle would be the same as the sine of the compliment to that angle... and vice versa. To answer this question, sin 81 = cos 9, since 81 and 9 are the two acute angles of the triangle and they both add up to 90 degrees. "Cos 9" is the answer when you wish to write "sin 81" in terms of "cosine."

Please give me brainiest

sine 81 degrees in terms of cosine is cos 9°

sin 81°

The angle is less than 90 degrees.it is an acute angle. Therefore, its in the first quadrant. The first quadrant, sine, cosine and tangent are positive.

sin 81° is less than 90 degree. Therefore, let's express them in terms of a cofunction.

Therefore,

sin x = cos(90 - x)

sin 81 = cos(90 - 81)

Therefore,

sin 81° = cos 9°

Answer:

1.1.1) -61

1.1.2) Term 42

Step-by-step explanation:

Tn= dn (difference) + t0 (term 0)

Tn= -4n+ 11

You can now take this general rule to find out the other terms.

Tn= -4(18)+11

Tn= -61

And the term -157

Tn= -4n+11

-157= -4n + 11

-157 - 11= - 4n

-168= -4n

-168/-4= n

42= n
