Answer:

depends upon the degree of the angle

Step-by-step explanation:

vertically opposite angles are always equal like

80 = 80 sum is equal to 160 degrees not equal to 90

45 = 45 , sums equal to 90 degrees ,equal to 90

30 = 30 sum is equal to 60 degrees, not equal to 90

so we can say it depends what is the no of degrees if it is 45 only we can say the vertically opposite angles are complementary angle

You start driving north for 7 miles, turn right, and drive east for another 24 miles. At the end of driving, what is your straig

horsena [70]

Answer:

$AC = 25\ miles$

Step-by-step explanation:

Given:

Distance for north side = 7 miles.

Distance for east side = 24 miles.

We need to find the displacement.

Solution:

Figure shows Point A is starting point and AB = 7 miles is North side distance and BC = 24 miles is east side distance and AC is shown as displacement.

Using Pythagoras theorem to find displacement (AC).

$(AC)^{2}=(AB)^{2}+(BC)^{2}$

Substitute AB = 7 and BC = 24 in above equation.

$(AC)^{2}=(7)^{2}+(24)^{2}$

$(AC)^{2}=49+576$

$(AC)^{2}=625$

$AC = \sqrt{625}$

$AC = 25\ miles$

Therefore, displacement of the car $AC = 25\ miles$

Find the circumference with the given radius.round to the nerest tenth.use 3.14 π r = 7cm

brilliants [131]

Answer:

44.0 cm.

Step-by-step explanation:

The formula for the circumference of a circle is

$C=2\pi r$

So we can substitute 7 for r and 3.14 for pi:

$C=2(3.14)(7)=43.96$ cm

And since we're rounding to the nearest tenth, the answer is 44.0 cm.

Georgia [21]

Answer:

$\mathrm{C.}$ 6 1/6

Step-by-step explanation:

(a + 2bc)/(3a)

Plug in the values.

(4 + 2(-5)(-7))/(3(4))

Evaluate.

(4 + 70)/12

ΔMNO is shown.

JulijaS [17]

Answer:

ABC - AAS

DEF - not enough information

GHI - not enough information

JKL - SAS

Step-by-step explanation:

SAS postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.

AAS postulate states that if two angles and the non-included side one triangle are congruent to two angles and the non-included side of another triangle, then these two triangles are congruent.

HL postulate states that if the hypotenuse and leg of one right triangle are congruent to the hypotenuse and leg of another right triangle, then the two triangles are congruent.

ASA postulate states that if two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the triangles are congruent.

SSS postulate states that if three sides of one triangle are congruent to three sides of another triangle, then the triangles are congruent.

1. In triangles MNO and ABC, there are two congruent sides and non-included angle - AAS

2. In triangles MNO and DEF, there are two congruent sides - there is not enough information

3. In triangles MNO and GHI, there are three congruent angles - there is not enough information

4. In triangles MNO and JKL, there are two congruent sides and included angle - SAS
