Answer:

1-Angle 1 and angle 8, angle 2 and angle 7.

2-Angle 3 and angle 6, angle 4 and angle 5.

3-Angle 1 and angle 5, angle 2 and angle 6.

4-Angle 2 and angle 3, angle 5 and angle 8.

Step-by-step explanation:

We are given that in diagram , transversal t cuts across the parallel lines a and b.

We have to match pair of angles with the relationship that show they are congruent.

Alternate interior angles:

Angle 3 and angle 6, angle 4 and angle 5.

Alternate exterior angles:

Angle 1 and angle 8, angle 2 and angle 7.

Corresponding angles:

Angle 1 and angle 5, angle 2 and angle 6.

Vertical angles:

Angle 2 and angle 3, angle 5 and angle 8.

hammer [34]

Answer:

22.6 feet

Step-by-step explanation:

Let x be the length of tree

tan(62) = x/12

x = 12tan(62)

In the triangle below, which is equivalent to sinA?

Sunny_sXe [5.5K]

1. By definition, you have:

Sin(α)=Opposite/Hypotenuse

2. Then, SinA is:

SinA=BC/AC

A is the angle in the vertice "A".
BC is the opposite leg to the the angle A.
AC is the hypotenuse of the triangle.

3. By definition, you have:

Cosα=Adjacent/Hypotenuse

4. Then, CosC is:

CosC=BC/AC

C is the angle at the vertice "C".
BC is the adjacent leg to the angle C.
AC is the hypotenuse.

5. Therefore, the answer is the last option:

The equivalent to SinA is CosC

Geometry, multiple choice. Answer all if possible. Ty.

12. The answer is B because the sum of any two sides of a triangle must be greater than the other side.
A. 4 → 4 + 4 is not GREATER than 8
B. 8 → 4 + 8 is greater than 8 and 8 + 8 is greater than 4
C. 12 → 4 + 8 is not GREATER than 12
D. 16 → 4 + 8 is not GREATER than 16

13. The central angle containing the green beans is 360° - (195°+98°) = 67°.
If the diameter of the circle is 12 then the circumference = πd = 12π.
$\frac{67}{360}$ × 12π≈7.013
So the correct answer is A
67/360 represents the portion of the circle which is green beans and you multiply it by the circumference to find the length of that arc.

The size 4 soccer ball Sean’s team uses should weigh no more than 0.37 kilograms, and no less than 0.31 kilograms. A soccer bag

dmitriy555 [2]

Answers:

Q: What is the most they could weigh together?

A: 0.74 kg

-----

Q: What is the least they could weigh together?

A: 0.62 kg

=================================================

Work Shown:

x = weight of first ball

y = weight of second ball

each ball has a weight range of 0.31 kg to 0.37 kg, so,

$0.31 \le x \le 0.37$

$0.31 \le y \le 0.37$

add straight down to get

$0.31+0.31 \le x+y \le 0.37+0.37$

which simplifies to

$0.62 \le x+y \le 0.74$

the two soccer balls have a weight range of 0.62 to 0.74, inclusive of both endpoints.

--------

Without using algebra, you basically just add the smallest the two weights could be (0.31) to itself to get 0.31+0.31 = 0.62 which represents the smallest the two weights combined can be. The same happens with the largest weight of 0.37 to get 0.37+0.37 = 0.74 as the max weight of both objects together.
