What is the answer to 3 + 4 1/10

1 answer:

4 0

First you can change 3 to 10/10 so that they can have the same denominator. Now, since you do that the number is now 2.

Now, do 10/10-1/10=9/10.
After do 2-4=-2.
So, your final answer is -2 9/10.

Find the missing lengths of the sides.

uranmaximum [27]

Answer:

b = 8√3 and c = 16

Step-by-step explanation:

<u>Points to remember</u>

If the angles of a right angled triangle with angles are 30°, 60, and 90 the their sides are in the ratio 1 : √3 : 2

<u>To find the unknown side lengths</u>

From the given figure we can see a right angled triangle

Angles are 30°, 60° and 90°

sides are in the ratio 1 : √3 : 2

1 : √3 : 2 = 8 : b : c

b = 8√3 and c = 8 * 2 = 16

Therefore b = 8√3 and c = 16

An angle measures 79.4 degrees more than the measure of its supplementary angle. What is the measure of each angle?

tatyana61 [14]

Answer:

The angles are: 50.3 and 129.7

Step-by-step explanation:

The sum of supplementary angles is 180°.

Let x be one angle then the other angle will be x+79.4

Using the supplementary angle sum

$x+x+79.4 = 180\\2x+79.4 = 180\\2x = 180-79.4\\2x = 100.6\\\frac{2x}{2} = \frac{100.6}{2}\\x = 50.3$

For the measurement of 2nd angle

x+79.4 => 50.3+79.4 => 129.7

Hence,

The angles are: 50.3 and 129.7
