Answer:

1.x=45,2.x=16

Step-by-step explanation:

1.

x+90+45=180(Angles in an adjacent angle)

x=180-135

x=45

2.

7x=112(vertically opposite angle)

x=112/7

x=16

First question refers to the supplementary angle theorem.

To find x, we need to refer to the other angles around it and use it to subtract it from 180°.

90 + 45 + x = 180

135 + x = 180

x = 180 - 135

x = 45°

Second question refers to the vertical angles theorem, where it states that the angles that face in opposite directions are the same.

7x = 112

x = 112 ÷ 7

x = 16°

Bogdan [553]
3 letters to US = 3*0.94 = 2.82
2 local letters = 2*0.44 =  0.88 
checking: 2.82+0.88 = 3.70

to get rid out of 0.04 cents you have to multiply it by 5. so total number of letters would be 5.

Solve equations by using elimination <br> -4+5y= 13<br> X-5y=21<br> ( , )
tigry1 [53]

Answer:

y=17/5 ,x= 38

Step-by-step explanation:

-4+5y =13 add 4 both side

4-4+5y=13+4

5y=17

5y/5=17/5 y=17/5

x-5y=21

x-5(17/5)=21

x-17=21

x=21+17= 38

Answer:

Step-by-step explanation:

A. If children are considered people under the age of 18, then the answer would be

13 < a < 18 where the a represents age, where the inequality signs do not have an equals to because those ages are excluded

B. This inequality can be shown on a number line with open circles denoting the endpoints 13 and 18 as they are not included, and a line connecting these two points which represents the ages encompassed by the range

Angle e measures 126LaTeX: ^\circ∘. What is the measure of LaTeX: \angle∠h?
SVEN [57.7K]

Answer:

m\angle h=126^o      

Step-by-step explanation:

we know hat

<u><em>Vertical Angles</em></u> are the angles opposite each other when two lines cross. They are always congruent.

In this problem

m\angle h=m\angle e ----> by vertical angles

we have

m\angle e=126^o ---> given problem

therefore

m\angle h=126^o
