We can find the side length of square 3 by dividing by 4, which is 9.

Then, we find the side length of square 2 by dividing it by 4, which is 12.

To find the AREA of square 1, we do a^2+b^2=c^2. This is basically adding up area of square 1 and square 2 to get square 3.

a^2+b^2=c^2
9^2+12^2=c^2
81+144=225

So the area is 225 units.

Answer:

225

Step-by-step explanation:

length of side in square 3 = 36/4

length of side in square 2 = 48/ 4

= 12

using pythagorus theorem you can find side of square 1

take the triangle between 3 and 2

9^2 + 12^2 = length of side 1^2

81 + 144 = l^2

225 = l^2

l = 15

therefore length of side 1 is 15

area of square 1 = 15^15

area = 225 square units

hope this helped

How would I do this?

Veseljchak [2.6K]

we know that the shaded side is 90 degrees and we are given 28 degrees

So we add 90+28 and we get 118

Since a triangle has 180 degrees, we subtract 180-118 to fins the missing angle measure

180-118=62

x=62

Your equation is 180=90+28+x

If 6/10 is multiplied by a fraction less than 1,which of these would be an answer 6/10,1/2,3/2,or 5

Pavlova-9 [17]

If $\frac{6}{10}$ is multiplied with a fraction less than 1, out of the given options $\frac{1}{2}$ would be the answer.

Explanation:

First, we need to determine what a fraction lesser than 1 is. If the numerator is lesser than the denominator, the fraction will be lesser than 1 whereas if the denominator is higher than the numerator is would equal more than 1.
If $\frac{6}{10}$ is multiplied with 1, we get the value $\frac{6}{10}$ . Since the fraction must be lesser than 1, $\frac{6}{10}$ cannot be an answer. So option 1 cannot be the answer.
The value of $\frac{6}{10}$ is 0.6. If it is multiplied with any value lesser than 1, the resulting value cannot be higher than the value of 0.6. The value of the fraction $\frac{3}{2}$ is 1.5 and the value of 5 are both greater than 0.6. So the third and fourth options cannot be the answer. So $\frac{1}{2}$ is the answer.

The sine of angle θ is 0.3.<br><br> What is cos(θ)?

Sergio [31]

The answer:

$\sqrt{9}1 /10$

Explanation to your question:

Since the sin of theta is 0.3, we can reasonably deduct that the opposite side to theta has a ration of 3 to 10 to that of the hypotenuse. Thus, the adjacent side to theta, using the pythagorean theorem, will be root91. Therefore, since the cosine of theta is the adjacent/hypotenuse, we get root 91/10
