Answer:

6) angle 4=110 degrees

7) angle 3=70 degrees

Step-by-step explanation:

6) angle 2=angle 4 because alternate adjacent angles are equal

7) angle 1=angle 3 because alternate adjacent angles are equal

angle 1+angle 3+angle 2+angle 4=360

angle 1+angle 3=360-110-110

2 angles 3=140

angle 3=70 degrees

$\\ \sf\longmapsto A=(1-4)-(2+1)$

$\\ \sf\longmapsto A=-3-3$

$\\ \sf\longmapsto A=-6$

$\\ \sf\longmapsto B=(3-\dfrac{1}{2})-(2-4)$

$\\ \sf\longmapsto B=\left(\dfrac{5}{2}\right)+2$

$\\ \sf\longmapsto B=\dfrac{5+4}{2}$

$\\ \sf\longmapsto B=\dfrac{9}{2}$

Now

$\\ \sf\longmapsto AB=-6\times \dfrac{9}{2}$

$\\ \sf\longmapsto AB=-3(9)$

$\\ \sf\longmapsto AB=-27$

BA

$\\ \sf\longmapsto \dfrac{9}{2}\times (-6)$

$\\ \sf\longmapsto 9(-3)$

$\\ \sf\longmapsto -27$

Observed:-

$\\ \sf\longmapsto AB=BA$

Two quantities, x and y, are directly proportional. If x is doubled, what happens to y?

vagabundo [1.1K]

Answer:

y is also doubled.

Step-by-step explanation:

Direct proportionality between $x$ and $y$ means that

$y \propto x$

or

$y=cx$ ,

which indicates a linear relationship between $x$ and $y$ because they are related by a constant.

Therefore, if x is doubled, then the new value of $y$ is $y_{new}$

$y_{new}=c(2x)$

$y_{new}=2(cx)$

$y_{new}=2y$

The new value of $y$ is 2 times the previous; therefore, $y$ is doubled as $x$ is doubled.

How do you find a if given c and 0 (angle) in a right triangle where a is the opposite, c is the hypotenuse, b is adjacent and 0

Yakvenalex [24]

C can be found using pythagoras theorem. c2=a2+b2. Now, b is not given, but we know that cos(theta)=b/c=>b=c*cos(theta). Substituting b in the above relation, c2=a2+c2(cos(theta))^2=>c2=a2/(1-cos((theta))^2). c is the squareroot of c2. Hence c=sqrt(2/(1-cos((theta))^2))

Sean tossed a coin off a bridge into the stream below. The path of the coin can be represented by the equation h = -16t2 + 72t +

Fiesta28 [93]

Answer:

100

Step-by-step explanation:

When t=0 (no time has passed), the coin is at height 100. This means the bridge must be 100 units high for this to be possible.
