both sides have a triangle so you don't need to worry about that

to balance the hanger, add what is missing:

the left is missing two circles

the right is missing a square

therefore, add 2 cicles to the left and a square to the right

Which expression represents the area of triangle ABC in square meters?
A. 1/2 x 14 x 57
B. 1/2 x 14 x 64
C. 1/2 x 24 x 40
D. 1/2 x 24 x 57

Answers

Answer:

A. 1/2 x 14 x 57

Step-by-step explanation:

The formula for the area of a triangle is base x height x 1/2

To calculate the base you would need to add the two numbers on the bottom of the triangle: 20 + 37 = 57

The photo shows that the height is 14 so it would be

1/2 x 14 x 57

Formula of area of triangle-1/2

The base is 20+37 =57

so the answer is 1/2*57*14

The measures of the angles of a triangle are shown in the figure below. Solve for x.
(2x+12)°
42°

Answers

2x + 12 = 42
-12. = -12
2x = 30
Divide by 2 = divided by 2
X= 15
That how you solve it
Answer: x=18
Explanation: So we know that when you add all angles together of a triangle it has to equal 180° and we know that one of the angles is 90° another is 42° and the last one is (2x+12)° so our equation would be
180=90+42+(2x+12)
add all the numbers that we can and get
180=2x+144
now subtract 144 from both sides so we could have the 2x by itself
36=2x
now to find the x we need to get rid of the 2 so we divide by 2 on both sides and get
18=x

The answer is two times of square root of 8
answer:

C: 400

explanation:

basically on the graph what you do is you find the first term in the two subject textbook title. so for physics - biology, you would go to the horizontal axis and find the physics section. then what you do is find the biology section on the vertical axis. find the square they intersect at. the number inside that square is the number of physics - biology books sold per month.

if you do the same thing for the history - chemistry books, you’ll find that 300 of those are sold per month.

the difference between 700 and 300 is 400, giving you option C as your answer.

Width = w = 3.4 in

height = h = 2

Total surface area of rectangular prism = 2*(lw + wh + hl)
