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

Ok so I have math homework and I need so help ASAP I need to find the average of 35 40 12 16 25 and 10 so could someone plz plz

sleet_krkn [62]

Answer: 23! Add your numbers, and divide that sum by the amount of numbers added to get average!

Step-by-step explanation:

The average is found by adding all numbers of the sample, and diving by the amount of numbers added. For example:

The average of 1, 2, and 3. You first add 1 + 2 + 3 to get 6.

You then divide 6 by the number of numbers added, being 3 (1, 2, and 3.).

6 / 3 = 2. The average of 1, 2, and 3 is 2.

In your case, you have 35, 40, 12, 16, 25, and 10.

First you add 35 + 40 + 12 + 16 + 25 + 10 to get 138.

Then you divide 138 by the amount of numbers you added: 6.

138 divided by 6 = 23 (138/6).

Hope this helps!

Add your numbers, and divide that sum by the amount of numbers added to get average!

Given that x square + 5 x + c is a perfect square find the value of C

lawyer [7]

Answer:

c = $\frac{25}{4}$

Step-by-step explanation:

To make a perfect square

add ( half the coefficient of the x- term )² to x² + 5x

x² + 5x + ( $\frac{5}{2}$ )²

= x² + 5x + $\frac{25}{4}$

= (x + $\frac{5}{2}$ )² ← a perfect square

Danny's Bike Shop sells a certain model of racing bike for $550. The same bike can be bought at a competing shop for 7 percent l

AleksAgata [21]

Answer:

$511.5

Step-by-step explanation:

Given: Selling price of bike at Danny´s shop is $550

Bike is sold 7% less at competitor´s shop.

Lets find the discounted amount at Danny´s competitor shop.

∴ $\frac{7}{100} \times 550 = \$ 38.5$

Now, finding the cost of bike at Danny´s competitor.

Cost of bike at Danny´competitor= $(\textrm{Price at dannys shop - discount provided by competitor})$

Cost of bike at Danny´s competitor= $550-38.5= \$511.5$

∴ Cost of bike at Danny´s competitor is $511.5.
