Step-by-step explanation:

a)42

b) triangle and Parallelogram

c) for triangle: (base× height)÷2

for Parallelogram: (base×height)

d) triangle: (6×6)÷2=18

Parallelogram: 6×4=24

18+24=42

if it is unclear or you need more explanation, ask freely. if the answer is correct please give me brainliest i need 3 brainliests

Answer:: A.) There are 15 full squares and 14 partial squares. It is not easy to count the partial squares. The top part has 6 half squares. They add up to 3. The partial squares at the bottom add up to 4. All together there are 42 full squares.

B.) there are two shapes: a right triangle at the top and a parallelogram at the bottom.

C.) The formula for the area of a triangle is A= bh/2. The Area of a parallelogram is A= bh.

D.) Using formulae-- A = 6×6/2

For the triangle part area is 18. For the parallelogram A = 6×4

That is 24. Adding the two shapes together, 18+24=42

Find w and y, will give brainliest for the correct answer
Alex Ar [27]

Answer: w=12, y=6√3

Step-by-step explanation:

Looking at the figure, we can split the triangle into 2 separate triangles. One on the left and one on the left. The triangle on the right is a 30-60-90 triangle. For this triangle, the hypotenuse is 2x in length. This is directly opposite of the right angle. The leg opposite to 30° is x in length. The leg opposite 60° is x√3 in length. Once you know the length of one side, you can plug in x to find the length of the other legs.

In this case, w and y are located on the same 30-60-90 triangle. Normally we would focus on that triangle to find our values, but in this instance, we don't have any values. We have to use the left triangle to find the leg that both triangles share.

The left triangle is a 45-45-90 triangle. For this triangle, the legs opposite of 45° is x in length. The hypotenuse is x√2. Since we know the hypotenuse, we can use it to find x.

x√2=8

x=8/√2

x=5.7 or 6       [Let's use 6 so that it is easier to work with a whole number]

Now that we know x, we can find w and y. Going back to the right triangle, we know the hypotenuse is 2x. We plug in 6 to find the length.

w=2x

w=2(6)

w=12

We know the leg opposite of 60° is x√3. We can plug in x.

y=6√3
