Find the value of x that makes lines u and v parallel, answer needed

Answers

Given:

u and v are parallel lines.

To find:

The value of x.

Solution:

If a transversal line intersect the two parallel lines, then

(1) Corresponding angles are congruent.

(2) Same sides interior angles are supplementary angles and their sum is 180 degrees.

15.

[tex]23x-2=90[/tex]           (Corresponding angles)

[tex]23x=90+2[/tex]

[tex]x=\dfrac{92}{23}[/tex]

[tex]x=4[/tex]

Therefore, the value of x is 4.

16.

[tex](x+106)+(x+86)=180[/tex]         (Same sided interior angles)

[tex]2x+192=180[/tex]

[tex]2x=180-192[/tex]

[tex]2x=-12[/tex]

Divide both sides by 2.

[tex]x=\dfrac{-12}{2}[/tex]

[tex]x=-6[/tex]

Therefore, the value of x is -6.

Clarence made a diagram to compare codominance and incomplete dominance. Which label belongs in the area marked Y? Neither allele is dominant. An intermediate phenotype is expressed in offspring. One allele is dominant over the other. Both dominant alleles are fully expressed in offspring.

Answers

Answer:

The correct answer is both dominant alleles are fully expressed in offspring.      

In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.  

In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.

Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.

88/8=11

i hope this one helps !!

Answer:

20,020 in. on the plans

Step-by-step explanation:

To get from 11 in. to 88 in. (from plans to real life), you multiply by 8.

Therefore, to get from 160,160 to ?? (from real-life to plans), you would divide by 8.

160,160 / 8 = 20,020

To check, you can multiply 20,020 by 8 to go from plans to real-life measurements; 20,020 • 8 = 160,160)
