What is the value of t<br><br> HELP
rusak2 [61]

Answer:

t = 8°

Step-by-step explanation:

We know that the sum of all the angles in a triangle is equal to 180°

Let's set up our equation => 18t + 36 = 180

Subtract 36 from both sides

18t = 144

t = 8

Thus, we have our answer

I really need help on this one, guys
Gennadij [26K]

Answer:

6.2 meters

Step-by-step explanation:

Use pythagorean theorem to find b:

b = √(2.8² - 2.7²) = √0.55 = 0.7 (nearest tenth)

Perimeter of triangle = sum of all its sides = 2.8 + 2.7 + 0.7

Perimeter = 6.2 meters

Jared uses 24 tiles to cover the top of his desk.of the 24 tiles,3/4 are blue. How many of the tiles are blue
rewona [7]
We multiply the fraction of 3/4 to the whole number 24 to get the equivalent number of the fraction.

24 * 3/4 = (24 * 3)/4 = 72/4 = 18

3/4 of 24 is 18.

There are 18 blue tiles out of the 24 tiles used.
