Answer:
The answer is <u>A) 36</u>
Step-by-step explanation:
Since 40% is equal to 0.4 of 1
You would multiply 90 by 0.4
Which is 36, which would give you answer A)
3. 180 - (53+68) = 59
The answer is B. 59°
4.
Part A: The measure of a is 70°.
Explanation: The angle sum in any triangle is 180°. 70 + 40 is 110. To find the final angle, subtract 110 from 180. 180 - 110 = 70
Part B: The length of x is 5m.
Explanation. The triangle is an isosceles triangle. We know this because the two angles on the base are equal. Since this is an isosceles triangle, the two longer sides are the same length. Therefore: x = 5 m.
Answer:
which is an irrational number
Step-by-step explanation:
Recall that the repeating decimal 0.7373737373... can be written in fraction form as: 
Now, let's write the number 147 which is inside the square root in factor form to find if it has some perfect square factors:

Then, 7 will be able to go outside the root when we compute the final product requested:

This is an irrational number due to the fact that it is the product of a rational number (quotient between 511 and 99) times the irrational number
