Answer:

Angle 3 is 113°

Step-by-step explanation:

Angles 2 & 3 is supplementary, so it equals 180°. Subtract 67 from 180 and you get 113. DUH.

Good Luck!!

Answer:

113°

Step-by-step explanation:

6 & 2 make a 180 ° angle

180-67 = 113

113° = angle 6

angle 6 is equivalent to angle 3

Step-by-step explanation:

start at 7 on the number line. move to the left (because the value is negative) 2 jumps. you will land on 5.

Answer: 5

Step-by-step explanation:

Usually you would just do 7+-2 which is also 7-2 which equals 5 but since it's a number line you do this

You would locate 7 on the number line and do the same for -2

Once done, you would take the distance 2 is from 0 and push 7 there(basically moving it to 5) and that would be how you would use a number line to find the sum of 7 + -2

Now if the 2 was positive, this would be different and you would add the distance making it 9 but since it's negative you push it towards 0 which makes it 5

Answer:

90 - 43 = x

Step-by-step explanation:

Answer: 47

Step-by-step explanation:

Dude just subtract 43 from 90, since you are given a 90 degree angle.

But if you need the equation: 43+x-7=90

add 43 and (-7) which gives us 36

new equation is now: 36+x=90

move the 36 to the other side

x=54

now plug it in x(54)-7=47

Answer: 49

Step-by-step explanation:

If 72% of the stamps he collected were

foreign, the percentage of the other stamps will be: = (100% - 72%) = 28%

Since the total number of stamps collected are 175, the number of other stamps collected will be:

= 28% of 175

= 28% × 175

= 28/100 × 175

= 0.28 × 175

= 49

Therefore, he collected 49 other stamps that were not foreign

Step-by-step explanation:

Answer:

<B = 95degrees

<D = 137 degrees

Step-by-step explanation:

From the given diagram, the sum of the adjacent sides of the trapezoid is 180degrees. Hence;

<A +<B = 180

85 + <B = 180

<B = 180 - 85

<B = 95degrees

Similarly

<C + <D =180

43 + <D = 180

<D = 180 - 43

<D = 137 degrees

Answer:

[tex]\overline {DC}[/tex] = 7

[tex]\overline {BD}[/tex] = √35

[tex]\overline {AB}[/tex] = 2·√15

Step-by-step explanation:

Please find attached the drawing of right triangle ABC created with MS Visio

Let 'x' represent [tex]\overline {BD}[/tex] let 'y' represent [tex]\overline {DC}[/tex], and let 'z' represent [tex]\overline {AB}[/tex], we get;

5² + x² = z²...(1)

x² + y² = (2·√21)² = 84

x² + y² = 84...(2)

84 + z² = (5 + y)²...(3)

From equation (1), we have;

x² = z² - 5²...(4)

From equation (2), and equation (4), we have;

x² + y² = 84 = (z² - 5²) + y² = 84

∴ z² = 84 - y² + 5² = 109 - y²

z² = 109 - y²...(5)

From equation (3), and equation (5), we have;

84 + z² = (5 + y)² = 84 + (109 - y²) = (5 + y)²

84 + (109 - y²) = (5 + y)²

(5 + y)² - (84 + (109 - y²)) = 0

2·y² + 10·y - 168 = 0

y² + 5·y - 84 = 0

y = (-5 ± √(5² - 4 × 1 × (-84)))/(2 × 1)

y = 7, or y = -12

We note that 'y' is a natural number, therefore, the correct option of the two options is y = 7

y = [tex]\overline {DC}[/tex] = 7

From equation (2), we have;

x² + y² = 84

x² = 84 - y² = 84 - 7² = 35

x = √35

x = [tex]\overline {BD}[/tex] = √35

z² = 109 - y²

∴ z² = 109 - 7² = 60

z = √60 = 2·√15

z = 2·√15

z = [tex]\overline {AB}[/tex] = 2·√15.

Answer:

Hypotenus property a2 +b2 =c2

Answer:

all radii of the same circle are congruent

tangents to a circle that intersect are congruent

side CO is congruent to side CO

SSS congruency theorem

Step-by-step explanation:

The triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.

Given: ∠AOB is a central angle and ∠ACB is a circumscribed angle.

A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.

We know that the radius and the tangent are perpendicular to each other.

Then the angle ∠CAO and angle ∠CBO are of 90°.

We know that the tangent of the circle drawn from the point outside the circle will be 2, and these tangent are of equal length.

In triangle △ACO ≅ △BCO, we have

CO = CO (Common side)

∠CAO = ∠CBO = 90°

OA = OB (Radius)

Thus, the triangle △ACO ≅ △BCO are congruent to each other by SAS postulate.

Answer:

  3 times the smaller triangle base

Step-by-step explanation:

The volume is proportional to the height and to the area of the base.

If the height is unchanged, the larger pyramid must have a triangular base with an area that is 9 times the smaller base area.

Since the bases are similar, the area ratio is the square of the side length ratio. The side lengths of the larger base triangle must be √9 = 3 times the side lengths of the smaller base triangle.

Answer:

77.5 degrees

Step-by-step explanation:

Answer:

A. 4x * 2x^2 + 4x * (-2) + 1 * 2x^2 + 1 * (-2)

Step-by-step explanation:

We have the binomial (4x + 1)(2x^2 - 2) and are asked to see how it looks like expanded.

When solving binomials, we need to follow the FOIL method :

First - First number in first parenthesis multiplied by first number in second parenthesis

Outer - First number in first parenthesis multiplied by second number in second parenthesis

Inner - Second number in first parenthesis multiplied by first number in second parenthesis

Last - Second number in first parenthesis multiplied by second number in second parenthesis

If we follow the definitions given, we can find our correct answer and also see where all the other answers mess up at :

A. 4x*2x^2+4x*(-2)+1*2x^2+1*(-2)

This follows FOIL entirely from start to finish.

B. 4x*2x^2+4x*(-2)+1*4x+1*(-2)

This did not follow the Inner part of FOIL.

C. 4x*2x^2+4x*(1)+1*2x^2+1*(-2)

This did not follow the Outer part of FOIL.
