Answer: okay me learning this right now so okay

Step-by-step explanation: I worked on the same problem and got it right last time!

Given the major arc and the minor arc share the same chord, the angle RST will be:

∠RST=1/2∠RHT

∠RHT=1/3π=1/3×180=60

hence

∠RST=1/2×60=30°

Answer: 30°

The sum of two numbers is eighteen. The total of three times the smaller and twice the larger is forty-four. Find the two number

sashaice [31]

Answer:

The numbers are 8 and 10.

Step-by-step explanation:

Let the numbers be x and y.

The sum of two numbers is eighteen:

x + y = 18

The total of three times the smaller and twice the larger is forty-four:

3x + 2y = 44

Solve the system by substitution:

x = 18 - y

Substitute x and solve for y:

3(18 - y) + 2y = 44
54- 3y + 2y = 44
54 - y = 44
y = 54 - 44
y = 10

Find x:

x = 18 - 10
x = 8

Factorize 2a^2+7a-15

loris [4]

$\huge\bf \pink {\underline{Solution :-}}$

$2 {a}^{2} + 7a - 15$

$= 2 {a}^{2} + 10a - 3a - 15$

$= 2a(a + 5) - 3(a + 5)$

$= (a + 5)(2a - 3)$

$\sf \red{Hence, Answer \: is \: (a + 5)(2a - 3).}$

$\\$

$\bf \purple{ \underline{ Important \: Formulas \: for \: Factorization :-}}$

$• \: {a}^{2} + 2ab + {b}^{2} = {(a + b)}^{2}$

$• \: (a + b)(a - b) = {a}^{2} - {b}^{2}$

$• \: {a}^{2} - 2 ab + {b}^{2} = {(a - b)}^{2}$

$• \: {a}^{3} + 3 {a}^{2} b + 3a {b}^{2} + {b}^{3} = {(a + b)}^{3}$

$• \: {a}^{3} - 3 {a}^{2} b + 3a {b}^{2} - {b}^{3} = {(a - b)}^{3}$

$• \: {(a + b)}^{2} + {(a - b)}^{2} = 2( {a}^{2} + {b}^{2} )$

$• \: {(a + b)}^{2} - {(a - b)}^{2} = 4ab$

$• \: (a + b)( {a}^{2} -ab + {b}^{2} ) = {a}^{3} + {b}^{3}$

$• \: (a - b)( {a}^{2} + ab + {b}^{2} ) = {a}^{3} - {b}^{3}$

$• \: {( \frac{a + b}{2} )}^{2} - ( {\frac{a - b}{2} } )^{2} = ab$
