Answer:

m∠2 = 18°

Step-by-step explanation:

Complementary angles: two angles that sum to 90°

⇒ m∠1 + m∠2 = 90°

⇒ 72° + m∠2 = 90°

⇒ m∠2 = 90° - 72°

⇒ m∠2 = 18°

The required value of is m∠2 = 18°.

Given that,

First complementary adjacent angel m∠1 = 72°

We have to find,

Second complementary adjacent angle m∠2.

According to the question,

In geometry, the two angles are said to be complementary angles if they add up to 90 degrees.

Such as, m∠1 + m∠2 = 90°.

Where, m∠1 = 72°

Putting the value of m∠1 = 72° in the equation,

72° + m∠2 = 90°

m∠2 = 90° - 72°

m∠2 = 18°

Hence, The required value of is m∠2 = 18°.

There are more than 15 shapes all together but no more than 25. There are 6 more squares than circles. There are 7 fewer circles

Ugo [173]

Answer:

the number of circles is 3

the number of square is 9

the number of triangle is 10

Step-by-step explanation:

Let the number of square = s

let the number of circle = c

let the number of triangle = t

let the total number of the shapes = y

15 < y < 25

y = s + c + t ---- (i)

s = c + 6 ------ (ii)

c + 7 = t ------ (iii)

y = (s) + (c) + (t)

y = (c + 6) + (c) + (c + 7)

y = 3c + 13

15 < y < 25

15 < 3c + 13 < 25

15 - 13 < 3c < 25 -13

2 < 3c < 12

2/3 < c < 12/3

0.67 < c < 4

Thus, number of circle is greater 1 but less than 4

c = 3

s = 3 + 6 = 9

t = 3 + 7 = 10

Use the way that kids use i.e trial and error method .

Solution:-

The set given by

$\\ \rm\longmapsto \left\{32+n,\dfrac{n}{8},\sqrt{n+225}\right\}$

Lets understand

See the first term any natural value will make it natural .

Come to 2nd one.

n should be a multiple of 8 to make it whole.

Come to third one

n should be a number which makes the sum a perfect square by which we get a natural no.We have to solve it w.r.t to 2nd one

Lets think

Nearest squares to 225 are 196 and 289

We can't take 196 as we have to take a positive one other wise it will come in terms of i.

Take 289

$\\ \rm\longmapsto n+225=289$

$\\ \rm\longmapsto n=289-225=64$

Its divisible by 8 .

Rewrite the set

$\\ \rm\longmapsto \left\{64+32,\dfrac{64}{8},\sqrt{225+64}\right\}$

$\\ \rm\longmapsto \left\{96,8,\sqrt{289}\right\}$

$\\ \rm\longmapsto \left\{96,8,17\right\}$

Hence n=64

You have an object with a mass of 14 grams and a volume of 3.5mL. What is the density of this object?

Goshia [24]

Answer:

density of given object is 4 g/m L

Step-by-step explanation:

<u>Density of given object</u>

Density is defined as mass per unit volume

the density of given object given mass and volume is

$density = \frac{mass}{volume}$

Given mass is 14 grams and Volume is 3.5 m L

Density = $\frac{14}{3.5}$

density of given object is 4 g/m L
