The angles in a triangle add up to 180 so if we add up 35 and 45 we get 80. subtract 80 from 180 and we are left with 100. So the answer is b

Answer:

The correct answer is option b.

Step-by-step explanation:

Given : Two out three angles of the triangle.

∠1 = 35°

∠2 = 45°

To find = Third angle of the triangle = ∠3 = ?

Solution :

∠1 +∠2 + ∠3 = 180° (Angle sum property of the triagkle )

∠3 = 180°-(∠1 +∠2)

∠3 = 180°- 35° - 45° = 100°

Hence, 100° is the measure of the third angle of the triangle.

Bought a board game for $30. The board game is now worth $55. Calculate the percent change in the game's value.
Hatshy [7]
30 is the old value and 55 is the new value. In this case we have a positive change (increase) of 83.33333333 percent because the new value is greater than the old value. Using this tool you can find the percent increase for any value.

Answers:

T-shirt = $25

Shorts = $15

Books = $50

Shoes = $30

Cell phones = $750

===============================================

Explanation:

Taking 10% of a number is simply moving the decimal point over one spot to the left.

For example, the selling price of a t-shirt is $250.00 and taking 10% of this gets us to $25.00

As another example, 10% of 150.0 is 15.0

If a whole number ends with a 0, then taking 10% of the number means we chop that zero off.
