valentinak56 [21]3 years ago

Answer:

Step-by-step explanation:

(1) 90 - 22 = 68

(2) 180 - 22 = 158

(3) 90 - 36 = 54

(4) 90

(5)90 - 24 = 66

(6) 24

(7) 15(complimentary angles are equal)

(8)90- 42 = 48

(9) E + F = 180(SUPPLEMENTARY ANGLES); E = 180 - 162 = 18

(10) G + H = 90(complementary angles); H= 90 - 18 = 72

(11)I + J= 180; J= 180 - 18 = 162

(12) K + L = 90; k = 90 - 42 = 48

The temperature at sunrise was -3*F. By noon, the temperature climbed 18 degrees. By sundown the temperature was -14*F. How much
Natalija [7]

Answer:

32*F

Step-by-step explanation:

* = degrees

Started at -3*F

By noon, the temperature climbed 18* = +18*

By sundown the temperature was -14*F

What we want to know: How much did the temperature drop between noon and sundown?

This is actually really easy!

What was the temperature at noon?        --> 18*F

What was the temperature at sundown? --> -14*F

So what is the difference between 18* and -14*? We can't use an equation, so we will solve manually.

The distance from -14 to 0 is 14 degrees. Keep that in mind.

The distance from 18 to 0 is 18 degrees. Keep that in mind.

So what is 14 + 18? 14 + 18 = 32*.

So, the temperature dropped 32*F between noon and sundown.

I hope this helps! I know this was a little messy, but that is because we couldn't use an equation/expression to solve this.

a square has a perimeter of 72 units. if its length measures 3y and its width measures 2x, what is the area of the square
erastova [34]

Answer:

324

Step-by-step explanation:

square has 4 sides.

perimeter adds all sides to make 72

72/4=18 units each side

length * width =area of square

square has all sides equal, so 3y and 2x are tricks to confuse. All sides are 18.

18*18= 324

Here is an easy one
kvv77 [185]
Remember that the angles of a triangle is 180 so:

(7x+8) + (5x+2) + (7x-1) = 180
7x+8+5x+2+7x-1=180
7x+5x+7x=180-8-2+1
19x=171
X= 171/19
X=9

Therefore x=9
