Answer:

\huge{ \boxed{ \bold{ \tt{x = 30 \degree}}}}

♨ Step - by - step explanation

☯ Given angles :

  • 2x° , 90° , x°

☯ To find :

  • Value of x

✎ Set up an equation and solve for x :

  • \sf{2x \degree \:  + 90 \degree \:  +  \: x \degree = 180 \degree}

Add the like terms. Remember that Only coefficients of like terms can be added or subtracted.

➺ \sf{3x \degree + 90 \degree = 180 \degree}

Move 90° to right hand side and change it's sign

➺ \sf{3x \degree  = 180 \degree - 90 \degree}

Subtract 90° from 180°

➺ \sf{3x \degree = 90 \degree}

Divide both sides by 3

➺ \sf{ \frac{3x \degree}{3}  =  \frac{90 \degree }{3} }

➺ \boxed{ \sf{x = 30 \degree}}

-------------------------------------------------------------------

❑ Rules for solving an equation

  • If an equation contains fractions , multiply each term by the LCM of denominators.
  • Remove the brackets, if any.
  • Collect the terms with the variable to the left hand side and constant terms to the right side by changing their signs ' + ' into ' - ' and ' - ' into ' + '.
  • Simplify and get the single term on each side.
  • Divide each side by the coefficient of variable and then get the value of variable.

Hope I helped!

Have a wonderful time ! ツ

Answer:

x = 30°

Step-by-step explanation:

2x + 90 + x = 180

3x = 90

x = 30

Discuss his principles of inheritance by answering the following questions. Two plants are being crossed, each heterozygous for
disa [49]

Answer:

Q1 - What is the possibility that the offspring will have white flowers? Express your answer as a ratio.

A: White flowers only appear if the offspring is homozygous for b because this phenotype is recessive, so they have to present bb phenotype. If both parents are heterozygous (Bb), each one gives one gene at a time per individual after crossing, so 1/4 would be BB, 2/4 would be Bb and 1/4 would be bb.

Q2 - If one parent is also heterozygous for smooth peas, does this mean that all of the offspring with blue flowers will also have smooth peas? Explain your answer without using a Punnett square.

A: No, it doesn't mean that all blue flowers will present smooth peas because those genes are expressed in different loci, so they segregate independently.  There might be some blue flowers with smooth peas, but that is not mandatory for all of them.

Q3 - Suppose both parents are also heterozygous for smooth peas (S), with wrinkled peas (s) as the recessive trait. Use a Punnett square to predict the possibility that the offspring will be homozygous for both flower color and pea texture. Make sure to include a Punnett square and express your prediction as a ratio.

A: Parental genotypes are BbSs x BbSs. Given that the genes segregate independently, we will have the Punnett diagram as follows:

        BS        /    Bs    /     bS   /   bs

BS    BBSS   / BBSs  / BbSS  / BbSs

Bs    BBSs   / BBss  / BbSs   / Bbss

bS    BbSS  / BbSs  / bbSS  / bbSs

bs     BbSs / Bbss  / bbSs  / bbss

Homozygous genotypes are the ones that both genes are the same when expressed, either BB,bb,SS or ss. The probability the offspring is homozygous for both flower color and pea texture is 4/16, or 1/4.

Solve the equation<br> 3x/ 8 - 4x/3 =4
Virty [35]

Answer:

x = -96/23

Step-by-step explanation

\frac{3x}{8} - \frac{4x}{3} = 4

multiply each side of equation by 24 to eliminate denominators

(24) \frac{3x}{8} - \frac{4x}{3} = 4 (24)

3(3x) - 8(4x) = 96

9x - 32x = 96

-23x = 96

x = -96/23

What are the vertical asymptote(s) of y= (x-6)/(x+8) (x-7)
White raven [17]

Answer:

x = -8 and x= 7

Step-by-step explanation:

recall that for a rational expression, the vertical asymptotes occur at x-values that causes the expression to become undefined. These occur when the denominator becomes zero.

Hence the asymptototes will occur in x-locations where the denominator , i.e

(x+8)(x-7) = 0

solving this, we get

(x+8) = 0 ----> x = -8

or

(x-7) = 0 ------> x = 7

hence the asymptotes occur x = -8 and x= 7
