Answer:

a=44^{\circ},b=136^{\circ},c=77^{\circ},d=57^{\circ}.

Step-by-step explanation:

It is given that a and 46° are complementary angles.

a+46^{\circ}=90^{\circ}

a=90^{\circ}-46^{\circ}

a=44^{\circ}

It is given that a and b are supplementary angles.

a+b=180^{\circ}

44^{\circ}+b=180^{\circ}

b=180^{\circ}-44^{\circ}

b=136^{\circ}

Angle conjugate to c is 283°.

c+283^{\circ}=360^{\circ}

c=360^{\circ}-283^{\circ}

c=77^{\circ}

Sum of all angles at a point is 360 degrees.

a+b+c+d+46^{\circ}=360^{\circ}

44^{\circ}+136^{\circ}+77^{\circ}+d+46^{\circ}=360^{\circ}

d+303^{\circ}=360^{\circ}

d=360^{\circ}-303^{\circ}

d=57^{\circ}

Therefore, a=44^{\circ},b=136^{\circ},c=77^{\circ},d=57^{\circ}.

Nuetrik [128]

Answer:

Percent markdown from 8$ to 5$ is 37.5%

Step-by-step explanation:

Given that the booster club is selling nahos at $8 price and in last 30 minutes to sell as many as possible, they lowered the price to 5$.

Percent mark down= \frac{decrease in price}{original price} X100

                                =\frac{8-5}{8} X100=\frac{3}{8}X100

                                =37.5

Hence percent markdown from 8$ to 5$ is 37.5%

Hendrick wants to enlarge a photo that is 4 inches wide and 6 inches tall. The enlarged photo keeps the same ratio. How y'all is
zhuklara [117]

Answer:

Step-by-step explanation:

Alright, lets get started.

The original photo size is 4 inches wide and 6 inches tall.

So, the ratio of width and height will be = \frac{4}{6}=\frac{2}{3}

The new enlarged photo will be of the same ratio means 2:3

The width of enlarged photo is given as 12 inches.

Suppose new height of enlarged photo is H, so

\frac{12}{H}=\frac{2}{3}

Cross multiplying

2H=36

Dividing 2 in both sides

H=18 inches

So the height of new enlagred photo will be 18 inches.  :   Answer

Hope it will help :)
