The triangle is (90 degrees) as we can see. We have found one side of three, which is equal to (60 degrees). All sides of a triangle add up to (180 degrees).
To find y and x, subtract 180 degrees from 60 degrees (180-60=120 degrees)
Remember, the triangle is a 90 degree angle, so one of the angles that add up to 120 is already 90 degrees, subtract 120-90 to get 30. Angle x is 30
To check: all triangles = 180 degrees
60+90+30= 180
You have now completed this question woohooooo time for me to continue my math, wish you all the best random internet stranger

Use estimation to help you choose the correct answer.<br><br> 0.945 x 7.6 =

hoa [83]

Remark

The thing you must not do is write 7.182 as your answer. That is the exact answer found using a calculator.

What to do.

What you should do is multiply two rounded numbers together.

7.6 rounded is 8 roughly

0.945 is almost 1.

Your answer is 8*1 = 8 roughly. This skill is very handy when you are writing a test and you want to see if you've done the question correctly. It is easy to misplace a decimal or put in incorrect digits and this is a quick check on things like that.

The legs of a 45 45 90 triangle have a length of 8 units what is the length of the hypotenous

Crank

Answer:

11.31 units

Step-by-step explanation:

a^2 + b^2 = c^2

8^2 + 8^2 = c^2

64 + 64 = c^2

128 = c^2

Opposite of exponents is square roots, and we need to get rid of that exponent in c^2, meaning we find the square root.

$\sqrt{128\\} \\\\$ = c

c = 11.31 units

Rates for having a manuscript typed at a certain typing service are $5 per page for the first time a page is typed and $3 per pa

Goryan [66]

Answer:

D. $680

Step By Step Explanation:

100 pages are typed. Each page coast $5 to type.

100 x 5 = 500

40 pages are revised once. It costs $3 to revise a page once.

40 x 3 = 120

10 pages are revised twice. It costs $3 to revise a page once so it will cost $6 to revise it twice

10 x 6 = 60

To find the total cost we add all the amounts together

500 + 120 + 60 = 680

The final answer is $680

The mass of a species of mouse commonly found in houses is normally distributed with a mean of 20.2 grams with a standard deviat

Sophie [7]

Answer:

12.1%

Step-by-step explanation:

Given that:

Mean (μ) = 20.2 grams and standard deviation (σ) = 0.18 grams.

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean. A positive z score means that the raw score is above the mean and a negative z score means that the raw score is below the mean. It is given by:

$z=\frac{x-\mu}{\sigma}$
