Calculate the value of the exterior angle

aev [14]

What we know is that the sum of a triangle's internal angles are 180º, and a straight angle makes 180º.

first, we have to find the third internal angle(let's call it n) so that we can use it to find the exterior angle.

(3x + 20) + (4x + 5) + n = 180

simplify:

7x + 25 + n = 180

7x + n = 155

n = 155 - 7x

Now we can add it to the external angle to find x.

(155 - 7x) + (8x + 15) = 180

simplify:

170 + 8x - 7x = 180

170 + x = 180

x = 10

Now we can substitute it to the external angle.

8 x 10 + 15 = 95

the exterior angle is 95º.

Point q is the image of Q(5, -3) after a translation down 2 units and right 4 units. What are the coordinates of Q?

Jet001 [13]

Answer:

(9,-5)

Step-by-step explanation:

When you go down, the number will decrease. The vertical position is the Y axis. -3-2=5.

When you go right, the number will increase. The horizontal position is the X axis. 5+4=9

(9,-5)

Hope this helps :-)

GuDViN [60]

Answer:

At the end of the party 5.5 gallons or 88 cups of punch will be leftover.

Step-by-step explanation:

Given:

There are 20 guest at a party.

Now, to find the quantity of punch that will be leftover.

Number of guests = 20.

Total gallons of punch = 8.

Now, using conversion factor we change gallons into cups:

1 gallon = 16 cup.

So, 8 gallons = 16 × 8 = 128 cups.

Thus, total cups of punch = 128.

Total number of cups each guest will drink = 2.

Now, to get total number of cups the 20 guests will drink by multiplying:

$20\times 2$

$=40\ cups.$

Total number of cups the 20 guests will drink = 40.

So, to get the leftover punch we subtract the total number of cups the 20 guests will drink from total cups of punch:

$128-40\\\\=88\ cups.$

So, 88 cups = $88\div 16=5.5\ gallons.$

Therefore, at the end of the party 5.5 gallons or 88 cups of punch will be leftover.
